Leviticus 22:21-23

“When a man presents a fellowship sacrifice to the LORD to fulfill a vow or as a freewill offering from the herd or flock, it has to be unblemished to be acceptable; there must be no defect in it. You are not to present any animal to the LORD that is blind, injured, maimed, or has a running sore, festering rash,  or scabs; you may not put any of them on the altar as a food offering to the LORD.  You may sacrifice as a freewill offering any animal from the herd or flock that has an elongated or stunted limb, but it is not acceptable as a vow offering.
