Matthew Henry on Leviticus 4:22-26

Those who have power to call others to account, are themselves accountable to the Ruler of rulers. The sin of the ruler, committed through ignorance, must come to his knowledge, either by the check of his own conscience, or by the reproof of his friends; both which even the best and greatest, not only should submit to, but be thankful for. That which I see not, teach thou me, and, Show me wherein I have erred, are prayers we should put up to God every day; that if, through ignorance, we fall into sin, we may not through ignorance abide in it.
