The Lord spoke to Moses, saying: Speak to Aaron and his sons, and to all the Israelite people, and say to them:
When any man of the house of Israel or of the strangers in Israel presents a burnt offering as his offering for any of the votive or any of the freewill offerings that they offer to the Lord, it must, to be acceptable in your favor, be a male without blemish, from cattle or sheep or goats. You shall not offer any that has a defect, for it will not be accepted in your favor.
And when a man offers, from the herd or the flock, a sacrifice of well-being to the Lord for an explicit vow or as a freewill offering, it must, to be acceptable, be without blemish; there must be no defect in it. Anything blind, or injured, or maimed, or with a wen, boil-scar, or scurvy--such you shall not offer to the Lord; you shall not put any of them on the altar as offerings by fire to the Lord. You may, however, present as a freewill offering an ox or a sheep with a limb extended or contracted; but it will not be accepted for a vow. You shall not offer to the Lord anything [with its testes] bruised or crushed or torn or cut. You shall have no such practices in your own land, nor shall you accept such [animals] from a foreigner for offering as food for your God, for they are mutilated, they have a defect; they shall not be accepted in your favor.
The Lord spoke to Moses, saying: When an ox or a sheep or a goat is born, it shall stay seven days with its mother, and from the eighth day on it shall be acceptable as an offering by fire to the Lord. However, no animal from the herd or from the flock shall be slaughtered on the same day with its young.
When you sacrifice a thanksgiving offering to the Lord, sacrifice it so that it may be acceptable in your favor. It shall be eaten on the same day; you shall not leave any of it until morning: I am the Lord.
You shall faithfully observe My commandments: I am the Lord. You shall not profane My holy name, that I may be sanctified in the midst of the Israelite people--I the Lord who sanctify you, I who brought you out of the land of Egypt to be your God, I the Lord.
