Lv 22:26-33

26^* The LORD said to Moses: 27When an ox or a lamb or a goat is born, it shall remain with its mother for seven days; only from the eighth day onward will it be acceptable, to be offered as an oblation to the LORD.^s 28You shall not slaughter an ox or a sheep on one and the same day with its young. 29Whenever you offer a thanksgiving sacrifice to the LORD, so offer it that it may be acceptable on your behalf; 30it must be eaten on the same day; none of it shall be left over until morning.^t I am the LORD.

31Be careful to observe my commandments. I am the LORD. 32Do not profane my holy name, that in the midst of the Israelites I may be hallowed. I, the LORD, make you holy, 33who led you out of the land of Egypt to be your God. I am the LORD.
