1 Corinthians 3:20

18 Let no one deceive himself. If any of you thinks he is wise in this age, he should become a fool, so that he may become wise.

19 For the wisdom of this world is foolishness in God’s sight. As it is written: “He catches the wise in their craftiness.”

And again, “The Lord knows that the thoughts of the wise are futile.”

21 Therefore, stop boasting in men. All things are yours,

22 whether Paul or Apollos or Cephas or the world or life or death or the present or the future. All of them belong to you,

Do read the surrounding verses too, because the context often says more than a single verse.
