Leviticus 22:2

That they separate themselves When any uncleanness is upon them, as appears from Leviticus 22:3. From the holy things This is the first caution. No priest, or other person, was to presume to eat any part of a consecrated victim, while he was under any degree of legal uncleanness. Neither were they, in that state, to eat of the first-fruits, which were also consecrated to God, Numbers 18:12. But they might eat of the tithes, which were allowed for their constant maintenance. That they profane not what they The children of Israel; hallow It ill became the priests to profane or pollute what the people hallowed.
