John Gill Commentary Leviticus 10:11

"and that ye may teach the children of Israel all the statutes which Jehovah hath spoken unto them by Moses." — Leviticus 10:11 (ASV)

And that you 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 has spoken unto them by the hand of Moses :
particularly those delivered and recorded in (Exodus 20:1–26) (22:1-23:33)

and as not the priests, so neither any other Israelite might instruct ^F19, 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 31:4Proverbs 31:5) .
