What differentiates this night from all [other] nights? On all [other] nights we eat chamets and matsa; this night, only matsa? On all [other] nights we eat other vegetables; tonight (only) marror. On all [other] nights, we don't dip [our food], even one time; tonight [we dip it] twice. On [all] other nights, we eat either sitting or reclining; tonight we all recline.

(26) And when your children ask you, ‘What do you mean by this rite?’(27) you shall say, ‘It is the passover sacrifice to Adonai, who passed over the houses of the Israelites in Egypt when smiting the Egyptians, but saved our houses.’ Those assembled then bowed low in homage.

(8) And you shall explain to your child on that day, ‘It is because of what Adonai did for me when I went free from Egypt.’

(14) And when, in time to come, a child of yours asks you, saying, ‘What does this mean?’ you shall reply, ‘It was with a mighty hand that Adonai brought us out from Egypt, the house of bondage.

(20) When, in time to come, your children ask you, “What mean the decrees, laws, and rules that our God Adonai has enjoined upon you?”(21) you shall say to your children, “We were slaves to Pharaoh in Egypt and Adonai freed us from Egypt with a mighty hand.(22)Adonai wrought before our eyes marvelous and destructive signs and portents in Egypt, against Pharaoh and all his household;(23) and us [God] freed from there, in order to take us and give us the land promised on oath to our fathers.

GEMARA:The Sages taught: If his son is wise and knows how to inquire, his son asks him. And if he is not wise, his wife asks him. And if even his wife is not capable of asking or if he has no wife, he asks himself. And even if two Torah scholars who know the halakhot of Passover are sitting together and there is no one else present to pose the questions, they ask each other.

The Gemara asks: Why does one remove the table? The school of Rabbi Yannai say: So that the children will notice that something is unusual and they will ask: Why is this night different from all other nights? The Gemara relates: Abaye was sitting before Rabba when he was still a child. He saw that they were removing the table from before him, and he said to those removing it: We have not yet eaten, and you are taking the table away from us? Rabba said to him: You have exempted us from reciting the questions of: Why is this night different [ma nishtana], as you have already asked what is special about the seder night.

(4) The attendants poured the second cup for the leader of the seder, and here the son asks his father the questions about the differences between Passover night and a regular night. And if the son does not have the intelligence to ask questions on his own, his father teaches him the questions: Why is this night different from all other nights? As on all other nights we eat leavened bread and matza; on this night all our bread is matza. As on all other nights we eat other vegetables; on this night we eat bitter herbs. As on all other nights we eat either roasted, stewed, or cooked meat, but on this night all the meat is the roasted meat of the Paschal lamb. As on all other nights we dip the vegetables in a liquid during the meal only once; however, on this night we dip twice.

MISHNAH: One mixes him the second cup, and here the son asks. If the son does not know how to ask, his father instructs him: What is the difference between this night and all other nights? For every night we dip once, but this night we dip twice. For every night we eat leavened and unleavened bread, but this night only unleavened. For in all other nights we eat meat roasted, preserved, or cooked, but in this night only roasted.

(1) We pour the second cup and remove the Seder plate as if we are done the Seder so the children will wonder and ask.

(2) Why is this night different from all other nights? On all other nights we don’t even dip once, and on this night, twice. On all other nights we eat chametz and matzah, and on this night, only matzah. On all other nights we eat many vegetables, and on this night, maror. On all other nights we eat and drink sitting and reclining, and on this night we all recline.

(11) And this is the law of the sacrifice of peace-offerings, which one may offer unto the LORD.(12) If he offer it for a thanksgiving, then he shall offer with the sacrifice of thanksgiving unleavened cakes mingled with oil, and unleavened wafers spread with oil, and (leavened) cakes mingled with oil, of fine flour soaked.

Rabban Gamliel would say: Anyone who did not saythese three matters on Passover has not fulfilled his obligation: The Paschal lamb, matza, and bitter herbs.

(3) Speak to all the congregation of Israel, saying: In the tenth day of this month every man shall take a lamb, according to their fathers’ houses, a lamb for a household;... (8) They shall eat the flesh that night, roast with fire and matzah; with bitter herbs they shall eat it.(9) Don't eat it raw, nor at all sodden with water, but roast with fire...

The mishna states that one of the questions is: Why is this night different from all other nights? As on all other nights we dip once; however, on this night we dip twice. Rava strongly objects to this statement of the mishna: Is that to say that on every other day there is no alternative but to dip once? Is there an obligation to dip at all on other days, as indicated by the wording of the mishna? Rather, Rava said that this is what the mishna is teaching: As on all other nights we are not obligated to dip even once; however, on this night we are obligated to dip twice.

Rav Safra strongly objects to this explanation: Is it obligatory for the children? As previously mentioned, the reason one dips twice is to encourage the children to ask questions. How can this be called an obligation? Rather, Rav Safra said that this is what the mishna is teaching: We do not normally dip even once; however, on this night we dip twice. This wording is preferable, as it indicates the performance of an optional act.

Therefore, the mishna teaches us that regardless [of the vegetable used] one requires two dippings, so that there be a conspicuous distinction for the children.

A person may not eat until it gets dark on the eve of Pesach [from] close to [the time of] the afternoon offering. Even the poorest person in Israel may not eat [on the eve of Pesach] until reclining [at the night's Seder]. And [the communal officers] must give them no fewer than four cups of wine, and [they must do so] even [if they receive funds] from the charity plate.
