17. And the Lord said to Moses,
18. Say to Aaron and his sons and to all the Israelites, Whoever of the house of Israel and of the foreigners in Israel brings his offering, whether to pay a vow or as a freewill offering which is offered to the Lord for a burnt offering
19. That you may be accepted, you shall offer a male without blemish of the young bulls, the sheep, or the goats.
20. But you shall not offer anything which has a blemish, for it will not be acceptable for you. [I Pet. 1:19.]
