Leviticus 21:22-24 American Standard Version (ASV)

22. He shall eat the bread of his God, both of the most holy, and of the holy:

23. only he shall not go in unto the veil, nor come nigh unto the altar, because he hath a blemish; that he profane not my sanctuaries: for I am Jehovah who sanctifieth them.

24. So Moses spake unto Aaron, and to his sons, and unto all the children of Israel.
