Let no one deceive himself
on 1 Corinthians 3:18-20
Paul closes the wisdom argument: whoever thinks he is wise in this age should become a fool, so that he may become wise. Job 5:13 and Psalm 94:11 follow, both turning human cleverness against itself.
This site's exposition
thoughts of the wise are futile
The second witness is Psalm 94:11. The psalm speaks of men, and Jamieson, Fausset and Brown note that Paul names the wise, the proud reasoners the psalm has in view. Chrysostom asks what further proof is needed when boundless Wisdom gives this verdict.
The record, by era
The Church Fathers2 voices
Next, he declares also the mode in which God took them, adding another testimony: "For the Lord," saith he, "knoweth the reasonings of men that they are vain." Now when the Wisdom which is boundless pronounces this edict concerning them, and declares them to be such, what other proof dost thou seek of their extreme folly? For men's judgments, it is true, in many instances fail; but the decree of God is unexceptionable and uncorrupt in every case.
Knowing that their thoughts are vain, God rebukes their wisdom in order to prove that they are foolish, showing that what they thought was false is true and vice versa.
The Medieval Church2 voices
Secondly, he proves what he had said by citing two authorities: the first of these is from Jb (5:13); hence he says: He catches the wise in their own craftiness. Now the Lord catches the wise in their own craftiness, because when they lay crafty …
If the Lord knows that the reasonings of men are vain, because there is nothing necessary and salvific in them, then how is it that you, Corinthians, harbor thoughts contrary to God and occupy yourselves with them as though they were profitable!
The Puritans and the Awakening1 voice
23 And ye are Christ's; and Christ is God's. Here the apostle founds an exhortation against over-valuing their teachers on what he had just said, and on the consideration that they had an equal interest in all their ministers: Therefore let no man glory in men (

The Lord knoweth the thoughts of the wise - They are always full of schemes and plans for earthly good; and God knows that all this is vain, empty, and unsatisfactory; and will stand them in no stead when he comes to take away their souls. This is a quotation from Psa 94:11. What is here said of the vanity of human knowledge is true of every kind of wisdom that leads not immediately to God himself.
A commentator
Jamieson, Fausset & Brown1802–1910
Commentary Critical and Explanatory on the Whole Bible (1871)
There it is of men; here it is "of the wise." Paul by inspiration states the class of men whose "thoughts" (or rather, "reasonings," as suits the Greek and the sense of the context) the Spirit designated in the Psalm, "vanity," namely, the "proud" (Ps 94:2) and worldly-wise, whom God in Ps 94:8 calls "fools," though they "boast themselves" of their wisdom in pushing their interests (Ps 94:4).

And again, - Psa 94:11. The Lord knoweth - God searches the heart. The particular thing which it is here said that he knows, is, that the thoughts of man are vain. They have this quality; and this is that which the psalmist here says that God sees. The affirmation is not one respecting the omniscience of God, but with respect to what God sees of the nature of the thoughts of the wise. The thoughts of the wise - Their plans, purposes, designs. That they are vain - That they lack real wisdom; they are foolish; they shall not be accomplished as they expect; or be seen to have that wisdom which they now suppose they possess.
