Devarim 16:1-3

Orthodox Jewish Bible

16 Be shomer of the month of Aviv [springtime, i.e., Nisan], and perform the Pesach offering unto Hashem Eloheicha; for in the month of Aviv Hashem Eloheicha brought thee forth out of Mitzrayim by lailah.

² Thou shalt therefore sacrifice the Pesach unto Hashem Eloheicha, of the tzon and the herd, in the place which Hashem shall choose to place Shmo there.

³ Thou shalt eat no chametz with it; shivat yamim shalt thou eat matzot therewith, even the lechem oni (bread of affliction); for thou camest forth out of Eretz Mitzrayim in haste in order that thou mayest remember the yom when thou camest forth out of Eretz Mitzrayim kol yemei chayyechah (all the days of thy life).
