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.
22 Do not offer to the Lord the blind, the injured or the maimed, or anything with warts or festering or running sores. Do not place any of these on the altar as a food offering presented to the Lord.
The thought of a seemingly endless slaughter of lambs can be unsettling for us. Just imagine how unsettling it must have been for those who participated in these bloody offerings! Yet because of sin, God required a sacrifice. He required a lamb. But not just any lamb. The lamb had to be spotless, without blemishes or defect (Lev. 22:21–22). In other words, it had to be perfect. -Anthony Clark
