Leviticus 22:20-22

201Whatever has a defect, you shall not offer, for it will not be accepted for you.

21When a man offers a sacrifice of peace offerings to the Lord 2to 3fulfill a special vow or for a freewill offering, of the herd or of the flock, it must be perfect to be accepted; there shall be no defect in it.

22Those that are blind or fractured or maimed or having a running sore or eczema or scabs, you shall not offer to the Lord, nor make of them an offering by fire on the altar to the Lord.
