17Speak to Aaron, saying, Whoever he be of your seed throughout their generations that has a blemish, let him not approach to offer the bread of his God. 18For whatever man he be that has a blemish, he shall not approach: a blind man, or a lame, or he that has a flat nose, or any deformity, 19or a man that is broken-footed, or broken-handed, 20or crook-backed, or a dwarf, or that has a blemish in his eye, or is scurvy, or scabbed, or has his stones broken; 21no man of the seed of Aaron the priest, that has a blemish, shall come near to offer the offerings of Yahweh made by fire: he has a blemish; he shall not come near to offer the bread of his God. 22He shall eat the bread of his God, both of the most holy, and of the holy: 23only he shall not go in to the veil, nor come near to the altar, because he has a blemish; that he not profane my sanctuaries: for I am Yahweh who sanctifies them. 24So Moses spoke to Aaron, and to his sons, and to all the children of Israel.
