Many precepts in our Law are the result of a similar course adopted by the same Supreme Being. It is, namely, impossible to go suddenly from one extreme to the other: it is therefore according to the nature of man impossible for him suddenly to discontinue everything to which he has been accustomed. Now God sent Moses to make [the Israelites] a kingdom of priests and a holy nation (Exod. 19:6) by means of the knowledge of God. Comp. “Unto thee it was showed that thou mightest know that the Lord is God (Deut. 4:35); “Know therefore this day, and consider it in thine heart, that the Lord is God” (ibid. 5:39). The Israelites were commanded to devote themselves to His service; comp. “and to serve him with all your heart” (ibid. 11:13); “and you shall serve the Lord your God” (Exod. 23:25); “and ye shall serve him” (Deut. 13:5). But the custom which was in those days general among all men, and the general mode of worship in which the Israelites were brought up, consisted in sacrificing animals in those temples which contained certain images, to bow down to those images, and to burn incense before them; religious and ascetic persons were in those days the persons that were devoted to the service in the temples erected to the stars, as has been explained by us. It was in accordance with the wisdom and plan of God, as displayed in the whole Creation, that He did not command us to give up and to discontinue all these manners of service; for to obey such a commandment it would have been contrary to the nature of man, who generally cleaves to that to which he is used; it would in those days have made the same impression as a prophet would make at present if he called us to the service of God and told us in His name, that we should not pray to Him, not fast, not seek His help in time of trouble; that we should serve Him in thought, and not by any action.

For this reason God allowed these kinds of service to continue; He transferred to His service that which had formerly served as a worship of created beings, and of things imaginary and unreal, and commanded us to serve Him in the same manner; viz., to build unto Him a temple; comp. “And they shall make unto me a sanctuary” (Exod. 25:8); to have the altar erected to His name; comp. “An altar of earth thou shalt make unto me” (ibid. 20:21); to offer the sacrifices to Him; comp. “If any man of you bring an offering unto the Lord” (Lev. 1:2), to bow down to Him and to burn incense before Him. He has forbidden to do any of these things to any other being; comp. “He who sacrificeth unto any God, save the Lord only, he shall be utterly destroyed” (Exod. 22:19); “For thou shalt bow down to no other God” (ibid. 34:14). He selected priests for the service in the temple; comp. “And they shall minister unto me in the priest’s office” (ibid. 28:41). He made it obligatory that certain gifts, called the gifts of the Levites and the priests, should be assigned to them for their maintenance while they are engaged in the service of the temple and its sacrifices. By this Divine plan it was effected that the traces of idolatry were blotted out, and the truly great principle of our faith, the Existence and Unity of God, was firmly established; this result was thus obtained without deterring or confusing the minds of the people by the abolition of the service to which they were accustomed and which alone was familiar to them.

I know that you will at first thought reject this idea and find it strange; you will put the following question to me in your heart: How can we suppose that Divine commandments, prohibitions, and important acts, which are fully explained, and for which certain seasons are fixed, should not have been commanded for their own sake, but only for the sake of some other thing: as if they were only the means which He employed for His primary object? What prevented Him from making His primary object a direct commandment to us, and to give us the capacity of obeying it? Those precepts which in your opinion are only the means and not the object would then have been unnecessary. Hear my answer, which win cure your heart of this disease and will show you the truth of that which I have pointed out to you. There occurs in the Law a passage which contains exactly the same idea; it is the following: “God led them not through the way of the land of the Philistines, although that was near; for God said, Lest peradventure the people repent when they see war, and they return to Egypt; but God led the people about, through the way of the wilderness of the Red Sea,” etc. (Exod. 13:17). Here God led the people about, away from the direct road which He originally intended, because He feared they might meet on that way with hardships too great for their ordinary strength; He took them by another road in order to obtain thereby His original object. In the same manner God refrained from prescribing what the people by their natural disposition would be incapable of obeying, and gave the above-mentioned commandments as a means of securing His chief object, viz., to spread a knowledge of Him [among the people], and to cause them to reject idolatry. It is contrary to man’s nature that he should suddenly abandon all the different kinds of Divine service and the different customs in which he has been brought up, and which have been so general, that they were considered as a matter of course; it would be just as if a person trained to work as a slave with mortar and bricks, or similar things, should interrupt his work, clean his hands, and at once fight with real giants. It was the result of God’s wisdom that the Israelites were led about in the wilderness till they acquired courage. For it is a well-known fact that travelling in the wilderness, and privation of bodily enjoyments, such as bathing, produce courage, whilst the reverse is the source of faint-heartedness: besides, another generation rose during the wanderings that had not been accustomed to degradation and slavery. All the travelling in the wilderness was regulated by Divine commands through Moses; comp. “At the commandment of the Lord they rested, and at the commandment of the Lord they journeyed; they kept the charge of the Lord and the commandment of the Lord by the hand of Moses” (Num. 9:23). In the same way the portion of the Law under discussion is the result of divine wisdom, according to which people are allowed to continue the kind of worship to which they have been accustomed, in order that they might acquire the true faith, which is the chief object [of God’s commandments].

Scripture tells us, according to the Version of Onkelos, that the Egyptians worshipped Aries, and therefore abstained from killing sheep, and held shepherds in contempt. Comp. “Behold we shall sacrifice the abomination of the Egyptians,” etc. (Exod. 8:26); “For every shepherd is an abomination to the Egyptians” (Gen. 46:34). Some sects among the Sabeans worshipped demons, and imagined that these assumed the form of goats, and called them therefore “goats” [se‘irim]. This worship was widespread. Comp. “And they shall no more offer their sacrifices unto demons, after whom they have gone a whoring” (Lev. 17:7). For this reason those sects abstained from eating goats’ flesh. Most idolaters objected to killing cattle, holding this species of animals in great estimation. Therefore the people of Hodu [Indians] up to this day do not slaughter cattle even in those countries where other animals are slaughtered. In order to eradicate these false principles, the Law commands us to offer sacrifices only of these three kinds: “Ye shall bring your offering of the cattle [viz.], of the herd and of the flock” (Lev. 1:2). Thus the very act which is considered by the heathen as the greatest crime, is the means of approaching God, and obtaining His pardon for our sins. In this manner, evil principles, the diseases of the human soul, are cured by other principles which are diametrically opposite.

This is also the reason why we were commanded to kill a lamb on Passover, and to sprinkle the blood thereof outside on the gates. We had to free ourselves of evil doctrines and to proclaim the opposite, viz., that the very act which was then considered as being the cause of death would be the cause of deliverance from death. Comp. “And the Lord will pass over the door, and will not suffer the destroyer to come unto your houses to suite you” (Exod. 12:23). Thus they were rewarded for performing openly a service every part of which was objected to by the idolaters.

To the above reason for the exclusive selection of the three kinds of animals for sacrifices, we may add the following, namely, that these species are animals which can be got very easily, contrary to the practice of idolaters that sacrifice lions, bears, and wild beasts, as is stated in the book Tomtom.

Now this verse mentions a reason for the offerings, namely, that they are a fire-offering, of a pleasing odor unto the Eternal. The Rabbi [Moshe ben Maimon] wrote in the Moreh Nebuchim that the reason for the offerings is because the Egyptians and the Chaldeans in whose lands the children of Israel were strangers and sojourners, used always to worship the herd and the flock, the Egyptians worshipping the sheep and the Chaldeans worshipping the demons whom they imagined as assuming the form of goats. To this day men of India never slaughter the herd. It was for this reason that He commanded [Israel] to slaughter these three species [of cattle: the herd, the flock, and the goats], to the Revered Name, so that it be known that the very act which the idol-worshippers considered to be the utmost sin [i.e., slaughtering the above species], that same act should be done as an offering before the Creator, and through it Israel’s sins would be forgiven. For such is the way to cure people of false beliefs, which are the diseasees of the human soul, for all diseases and sicknesses are healed by medicines which are antithetical to them. These are the words [the Rabbi Moshe ben Maimon], and he expounded them at great length.
But these words are mere expressions, healing casually a severe wound and a great difficulty, and making the table of the Eternal polluted, [as if the offerings were intended only] to remove false beliefs from the hearts of the wicked and fools of the world, when Scripture says that they are the food of the offering made by fire, for a pleasing odor. Moreover, [if the offerings were meant to eliminate] the foolish [ideas] of the Egyptians, their disease would not thereby be cured. On the contrary, it would increase the cause of sorrow, for since the intention of the above-mentioned wicked ones was to worship the constellations of the sheep and the ox, which according to their opinion possess certain powers [over human affairs], and which is why they abstain from eating them in deference to their power and strength, then if these species are slaughtered to the Revered Name, it is a mark of respect and honor to [these constellations]. These worshippers themselves were in the habit of so doing, as He has said, And they shall no more sacrifice their sacrifices unto the satyrs, and those who made the [golden] calf sacrificed to it. Now the Rabbi [Moshe ben Maimon] mentions that the idol-worshippers used to sacrifice to the moon on the days of new-moon, and to the sun when it rose in a particular constellation known to them from their books. The disease of idolatry would surely have been far better cured if we were to eat [these animal-deities] to our full, which would be considered by them forbidden and repugnant, and something they would never do!
Furthermore, when Noah came out of the ark with his three sons, there were as yet no Chaldeans or Egyptians in the world, yet he brought an offering, which was pleasing to G-d, as concerning it Scripture says, And the Eternal smelled the pleasing odor, and on account of it He said in His heart, ‘I will not again curse the ground any more for man’s sake.’ Abel likewise brought of the first-born of his flock and of the fat thereof. And the Eternal had regard unto Abel and to his offering. Yet there was as yet not the slightest trace at all of idol-worship in the world! Balaam said, ‘I have prepared the seven altars, and I have offered up a bullock and a ram on every altar.’ His intent then was not to eradicate from [Balak’s mind] evil beliefs, nor was he commanded to bring the offerings. Instead, Balaam did so in order to approach G-d so that he would be reached by His communication. The Scriptural expression concerning the offerings is, My food which is presented unto Me for offerings made by fire, for a pleasing odor unto Me. Far be it that they should have no other purpose and intention except the elimination of idolatrous opinions from the minds of fools!
It is far more fitting to accept the reason for the offerings which scholars say, namely that since man’s deeds are accomplished through thought, speech and action, therefore G-d commanded that when man sins and brings an offering, he should lay his hands upon it in contrast to the [evil] deed [committed]. He should confess his sin verbally in contrast to his [evil] speech, and he should burn the inwards and the kidneys [of the offering] in fire because they are the instruments of thought and desire in the human being. He should burn the legs [of the offering] since they correspond to the hands and feet of a person, which do all his work. He should sprinkle the blood upon the altar, which is analogous to the blood in his body. All these acts are performed in order that when they are done, a person should realize that he has sinned against his G-d with his body and his soul, and that “his” blood should really be spilled and “his” body burned, were it not for the loving-kindness of the Creator, Who took from him a substitute and a ransom, namely this offering, so that its blood should be in place of his blood, its life in place of his life, and that the chief limbs of the offering should be in place of the chief parts of his body. The portions [given from the sin-offering to the priests], are in order to support the teachers of the Torah, so that they pray on his behalf. The reason for the Daily public Offering is that it is impossible for the public [as a whole] to continually avoid sin. Now these are words which are worthy to be accepted, appealing to the heart as do words of Agadah.
