1 Corinthians 3:18-20

18Let no one deceive himself. If anyone among you thinks that he is wise in this age, let him become a fool [discarding his worldly pretensions and acknowledging his lack of wisdom], so that he may become [truly] wise.

19For the wisdom of this world is foolishness (absurdity, stupidity) before God; for it is written [in Scripture], “[He is] The one who catches the wise and clever in their craftiness;”

20and again, “The Lord knows the thoughts of the [humanly] wise, that they are useless.”
