Levítico 22:21

21 When anyone brings from the herd or flock a fellowship offering to the Lord to fulfill a special vow or as a freewill offering, it must be without defect or blemish to be acceptable.

21 And whosoever offereth a sacrifice of peace-offerings unto Jehovah to accomplish a vow, or for a freewill-offering, of the herd or of the flock, it shall be perfect to be accepted; there shall be no blemish therein.
