Leviticus 10:11
And that ye may teach the children of Israel all the statutes which the LORD hath spoken unto them by the hand of Moses.
And that ye may teach the children of Israel all the statutes,.... Laws, precepts, ordinances, moral, ceremonial, and judicial, which was the business of the priests to do, Malachi 2:7 but one inebriated with liquor would be incapable of giving instructions about any of those things:
which the LORD hath spoken unto them by the hand of Moses: particularly those delivered and recorded in Exodus 20:1 and as not the priests, so neither any other Israelite might instruct {s}, nor indeed would be capable of instructing others when in liquor; and therefore excessive drinking, as it should be carefully avoided by all men, so more especially by those who by their office are teachers of others; see Proverbs 31:4.
