Leviticus 22:26

24You must not offer to the LORD that which has its testicles bruised, crushed, broken, or cut. You must not do this in your land.

25You must not offer any of these as the bread of your God from the hand of a foreigner, because their corruption is in them. There is a defect in them. They shall not be accepted for you.’”

26The LORD spoke to Moses, saying,

27“When a bull, a sheep, or a goat is born, it shall remain seven days with its mother. From the eighth day on it shall be accepted for the offering of an offering made by fire to the LORD.

28Whether it is a cow or ewe, you shall not kill it and its young both in one day.
