Leviticus 22:25-29

nor shall you offer any of these animals taken from the hand of a foreigner as the food of your God; for their deformity is in them, they have an impairment. They will not be accepted for you.’ ”

Then the Lord spoke to Moses, saying,

“When an ox or a sheep or a goat is born, it shall remain seven days with its mother, and from the eighth day on it will be considered acceptable as a sacrifice of an offering by fire to the Lord.

But, whether it is an ox or a sheep, you shall not slaughter both it and its young in one day.

When you sacrifice a sacrifice of thanksgiving to the Lord, you shall sacrifice it so that you may be accepted.
