Commentary
Matthew Henry on Psalms 94:1-11
In these verses we have,
I. A solemn appeal to God against the cruel oppressors of his people, Psa 94:1, Psa 94:2. This speaks terror enough to them, that they have the prayers of God's people against them, who cry day and night to him to avenge them of their adversaries; and shall he not avenge them speedily? Luk 18:3, Luk 18:7. Observe here,
1. The titles they give to God for the encouraging of their faith in this appeal: O God! to whom vengeance belongeth; and thou Judge of the earth. We may with boldness appeal to him; for, (1.) He is judge, supreme judge, judge alone, from whom every man's judgment proceeds. He that gives law gives sentence upon every man according to his works, by the…
The Lord knoweth the thoughts of man,.... He not only hears their words, and sees their actions; but he knows their thoughts, the secret thoughts of their hearts, though he is afar off from them, and, they from him; he is the searcher of the hearts and trier of the reins of the children of men; see Psalm 139:2, and so is Christ, who is the omniscient God, and is the Jehovah all along spoken to and of in this psalm; he knows the thoughts of men, and is a critical discerner of them, Matthew 9:3.
that they are vanity; either that their thoughts are vanity; the object of them is vanity, the riches and honours of this world, which are all vanity and vexation of spirit; and sinful lusts and pleas…
Psalm 94:11-13
11. Jehovah knoweth the thoughts of men, [24] that they are vain. [25] 12. Blessed is the man whom thou hast instructed, O God! And taught out of thy law; 13. To give him rest from days of evil whilst the pit is digged for the wicked.
11. Jehovah knoweth the thoughts of men, etc. He again insists upon the folly of men in seeking to wrap themselves up in darkness, and hide themselves from the view of God. To prevent them from flattering themselves with vain pretexts, he reminds them that the mists of delusion will be scattered at once when they come to stand in God's presence. Nothing can avail them, so long as God from heaven stamps vanity upon their deepest counsels. The Ps…
The Church Fathers
"The Lord knows the thoughts of men, that they are vain." Men marvel at the philosophers and poets who say: "O the cares of men! O how much emptiness there is in things!" Behold, the psalm of David, many ages before, spoke the same sentiment. "The Lord knows the thoughts of men, that they are vain." As long as we are men, we have vain thoughts. "I said, You are gods, and all of you sons of the Most High."
"The Lord knows the thoughts of man, that they are but vain" [Psalm 94:11]. For although you know not the thoughts of God, that they are righteous; "He knows the thoughts of man, that they are but vain." Even men have known the thoughts of God: but those to whom He has become a friend, it is to them He shows His counsel. Do not, brethren, despise yourselves: if you approach the Lord with faith, you hear the thoughts of God; these you are now learning, this is told you, and for this reason you are taught, why God spares the wicked in this life, that you may not murmur against God, who teaches man knowledge. "The Lord knows the thoughts of man, that they are but vain." Abandon therefore the thoughts of man, which are vain: that you may take hold on the thoughts of God, which are wise. But who is he who takes hold on the thoughts of God? He who is placed in the firmament of heaven. We have already chanted that Psalm, and have expounded this expression therein.
People argue against this evident truth. What else, after all, could you expect from mere people, who savor the things of humankind, but to argue about God against God? I mean, he is God, they are mere individuals. But God "knows the thoughts of people, that they are vain." With worldly, materialistic people, what they are in the habit of observing entirely governs their manner of understanding. What they are accustomed to see, they can believe; what they aren't, they can't. God performs miracles that go beyond what we are accustomed to, because he is God. It is in fact a greater miracle, so many people being born every day who did not previously exist, than a few having risen again, who did exist; and yet this kind of miracle is not seriously considered and appreciated, but being so common is disregarded as uninteresting. Christ rose again; the case is complete and closed. He was body, he was flesh, which hung on the cross, gave up the soul, was placed in the tomb. He presented it alive, seeing he lived in it. Why are we astonished, why don't we believe? It is God who did it. Reflect on the one who brought it about, and you eliminate all possibility of doubt.

The third strophe now turns from those bloodthirsty, blasphemous oppressors of the people of God whose conduct calls forth the vengeance of Jahve, to those among the people themselves, who have been puzzled about the omniscience and indirectly about the righteousness of God by the fact that this vengeance is delayed. They are called בערים and כסילים in the sense of Psa 73:21. Those hitherto described against whom God's vengeance is supplicated are this also; but this appellation would be too one-sided for them, and בּעם refers the address expressly to a class of men among the people whom those oppress and slay. It is absurd that God, the planter of the ear (הנּטע, like שׁסע in Lev 11:7, with…
While the Lord’s thoughts are deep, people’s thoughts are worthless (cp. 92:5; 1 Cor 3:20).
Spurgeon's Treasury of David on Psalms 94:11
The Lord knoweth the thoughts of man, that they are vanity.
Whether men admit or deny that God knows, one thing is here declared, namely, that The Lord knoweth the thoughts of man, that they are vanity. Not their words alone are heard, and their works seen, but he reads the secret motions of their minds, for men themselves are not hard to be discerned of him, before his glance they themselves are but vanity. It is in the Lord's esteem no great matter to know the thoughts of such transparent pieces of vanity as mankind are, he sums them up in a moment as poor vain things. This is the sense of the original, but that given in the authorised version is also true—the thoughts, the best part, the…
