Vayikra 22:28-30

Orthodox Jewish Bible

²⁸ And whether it be an ox or seh, ye shall not slaughter (shachat) it and her young both in yom echad.

²⁹ And when ye will offer a zevach todah unto Hashem, offer it liretzonechem (for your acceptance [before Hashem]).

³⁰ On the same day it shall be eaten; ye shall leave none of it until the boker: I am Hashem.
