Leviticus 22:25-30

²⁵Neither from the hand of a foreigner shall ye offer the bread of your God of any of these; because their corruption is in them, there is a blemish in them: they shall not be accepted for you.

²⁶And Jehovah spake unto Moses, saying,

²⁷When a bullock, or a sheep, or a goat, is brought forth, then it shall be seven days under the dam; and from the eighth day and thenceforth it shall be accepted for the oblation of an offering made by fire unto Jehovah.

²⁸And whether it be cow or ewe, ye shall not kill it and its young both in one day.

²⁹And when ye sacrifice a sacrifice of thanksgiving unto Jehovah, ye shall sacrifice it that ye may be accepted.

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