Leviticus 22
21 Ref Whoever offers a sacrifice of peace offerings to Yahweh 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.
22 Ref Blind, injured, maimed, having a wart, festering, or having a running sore, you shall not offer these to Yahweh, nor make an offering by fire of them on the altar to Yahweh.
23 Ref Either a bull or a lamb that has any deformity or lacking in his parts, that you may offer for a freewill offering; but for a vow it shall not be accepted.
