(10) since you will be heeding the LORD your God and keeping His commandments and laws that are recorded in this book of the Teaching—once you return to the LORD your God with all your heart and soul. (11) Surely, this Instruction which I enjoin upon you this day is not too baffling for you, nor is it beyond reach. (12) It is not in the heavens, that you should say, “Who among us can go up to the heavens and get it for us and impart it to us, that we may observe it?” (13) Neither is it beyond the sea, that you should say, “Who among us can cross to the other side of the sea and get it for us and impart it to us, that we may observe it?” (14) No, the thing is very close to you, in your mouth and in your heart, to observe it. (15) See, I set before you this day life and prosperity, death and adversity. (16) For I command you this day, to love the LORD your God, to walk in His ways, and to keep His commandments, His laws, and His rules, that you may thrive and increase, and that the LORD your God may bless you in the land that you are about to enter and possess. (17) But if your heart turns away and you give no heed, and are lured into the worship and service of other gods, (18) I declare to you this day that you shall certainly perish; you shall not long endure on the soil that you are crossing the Jordan to enter and possess. (19) I call heaven and earth to witness against you this day: I have put before you life and death, blessing and curse. Choose life—if you and your offspring would live— (20) by loving the LORD your God, heeding His commands, and holding fast to Him. For thereby you shall have life and shall long endure upon the soil that the LORD swore to your ancestors, Abraham, Isaac, and Jacob, to give to them.

We learned in our mishna the explanation of the verse: “And you shall love the Lord your God with all your heart and all your soul and all your might” (Deuteronomy 6:5). This was elaborated upon when it was taught in a baraita: Rabbi Eliezer says: If it is stated: “With all your soul,” why does it state: “With all your might”? Conversely, if it stated: “With all your might,” why does it state: “With all your soul”? Rather, this means that if one’s body is dearer to him than his property, therefore it is stated: “With all your soul”; one must give his soul in sanctification of God. And if one’s money is dearer to him than his body, therefore it is stated: “With all your might”; with all your assets. Rabbi Akiva says: “With all your soul” means: Even if God takes your soul.

The Gemara relates at length how Rabbi Akiva fulfilled these directives. The Sages taught: One time, after the bar Kokheva rebellion, the evil empire of Rome decreed that Israel may not engage in the study and practice of Torah. Pappos ben Yehuda came and found Rabbi Akiva, who was convening assemblies in public and engaging in Torah study. Pappos said to him: Akiva, are you not afraid of the empire? Rabbi Akiva answered him: I will relate a parable. To what can this be compared?

It is like a fox walking along a riverbank when he sees fish gathering and fleeing from place to place.
The fox said to them: From what are you fleeing?
They said to him: We are fleeing from the nets that people cast upon us.
He said to them: Do you wish to come up onto dry land, and we will reside together just as my ancestors resided with your ancestors?
The fish said to him: You are the one of whom they say, he is the cleverest of animals? You are not clever; you are a fool. If we are afraid in the water, our natural habitat which gives us life, then in a habitat that causes our death, all the more so.
The moral is: So too, we Jews, now that we sit and engage in Torah study, about which it is written: “For that is your life, and the length of your days” (Deuteronomy 30:20), we fear the empire to this extent; if we proceed to sit idle from its study, as its abandonment is the habitat that causes our death, all the more so will we fear the empire.
