John Wesley on Ecclesiastes 7:16

Be not - This verse and the next have a manifest reference to ver.15, being two inferences drawn from the two clauses of the observation. Solomon here speaks in the person of an ungodly man, who takes occasion to dissuade men from righteousness, because of the danger which attends it. Therefore, saith he, take heed of strictness, zeal, and forwardness in religion. And the next verse contains an antidote to this suggestion; yea, rather saith he, be not wicked or foolish overmuch; for that will not preserve thee, as thou mayest imagine, but will occasion and hasten thy ruin.
