Leviticus
King James Version (KJV)

“When 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 an offering made by fire unto the LORD.”
King James Version (KJV)
22:25 A stranger's hand - From proselytes: even from those, such should not be accepted, much less from the Israelites. The bread of your God - That is, the sacrifices.
22:28 In one day - Because it favoured of cruelty.
