I hate all that give heed to lying vanities. In order the better to express that his faith was firmly fixed on God, he affirms that he was free from the vile affections which usually turn away our minds from God, and under which unbelievers for the most part labor. For we know that by contrasting things which are opposite, a subject is better illustrated. To restrict the Hebrew word hvl, hebel, which we have rendered vanities, to magical arts, as some interpreters do, is absurd. [1] I confess, indeed, that the Orientals were so much addicted to these impostures, that it was a common evil among them. But as the devices by which Satan ensnares the minds of men, and the allurements by which he draws them away from God, are innumerable, it is not at all probable that the prophet mentions one species only. Whatever vain hopes, therefore, we form to ourselves, which may draw us off from our confidence in God, David generally denominates vanities, yea, false or lying vanities, because, although they feed us for a time with magnificent promises, in the end they beguile and disappoint us. He affirms, therefore, that casting away the vanities which men usually invent to support their hopes, he relies solely on God. And as men not only intoxicate themselves personally with the deceitful allurements of the world, but in this respect also deceive one another, the prophet expressly declares, with a view that we may carefully avoid them, unless we wish to be wilfully entangled in their dangerous toils, that he hated all who involved themselves in such lies. The second clause, I have trusted in Jehovah, must be read in connection with the first, because it both assigns the cause of his hatred of lying vanities, and shows that it is impossible for men to have any true faith in God, unless they abhor whatever would draw them away from him.

Footnotes

1 - Hammond considers "vanities" as referring to the practice of superstitiously having recourse to auguries and divinations for advice and direction, a practice which prevailed among the heathen, when they met with any difficulty or danger. To the responses of augury, they showed the greatest regard; although they were deceived and disappointed in the confidence which they reposed in them. David declares that he detested all such practices, and trusted for aid to God alone. French and Skinner, by lying vanities, understand idols. "Idols," says Walford, "are often thus denominated; though the term is not to be confined to this sense, as all the pursuits of iniquity may be justly comprehended under it. - Vide Deuteronomy 32:21; Jonah 2:8."

I have hated them that regard lying vanities - This is evidently stated as a reason for the prayer offered in the previous verses. It is a reference by the psalmist to his own past life; to his general aim and conduct. The meaning is, that he had been a friend of God; that he had separated himself from wicked men; and he now prays in return for His protection and interposition. The sentiment is similar to that which occurs in Psalm 26:3-5. See the notes at that passage. The word rendered "regard" here means to observe, to keep, to attend upon; and the reference is to those who show honor to what is here called "lying vanities;" that is, those who attend upon them, or who show them favor. The "lying vanities" are probably "idols," and the allusion is to those who attended on the worship of idols as distinguished from those who worshipped the true God. Idols are often represented as false - as vain, or vanity, - as a lie - in contradistinction from that which is true and real. See the notes at 1-Corinthians 8:4. There is special emphasis in the language used here as denoting the "utter" worthlessness and vanity of idols. The language means "vanities of emptiness;" denoting that they were "utterly" vain and worthless.
But I trust in the Lord - In Yahweh, the true God, as distinguished from idols.

I have hated them - That is, I have abominated their ways. Idolaters are the persons of whom David speaks.
I trust in the Lord - While they trust in vanities vain things; (for an idol is nothing in the worid); and in lying vanities; (for much is promised and nothing given); I trust in Jehovah, who is God all-sufficient, and is my Shepherd, and therefore I shall lack no good thing.

I have hated them that regard lying vanities: but I (d) trust in the LORD.
(d) This affection should be in all God's children to hate whatever is not grounded on a sure trust in God, as deceitful and vain.

I have hated them that regard lying vanities,.... Soothsaying and divination, as Aben Ezra and others think; made use of by kings, and generals of armies, to know when it was proper to go out to war, and what success they should have; see Ezekiel 21:21; but such men and their practices David abhorred; he took no such methods when in distress, but applied to the Lord, and trusted in him; or rather idol gods, as Jarchi, and others, who are vanity, and the work of errors, and are nothing in the world; see Jonah 2:8; all will worship and superstition may be included in this phrase, which being not according to the will and word of God, is worshipping in vain, and carries off from true spiritual worship; and so is a lying vanity, and to be detested, and the abettors of it: as also all errors and heresies; these are great swelling words of vanity, and are lies in hypocrisy; and likewise all immorality and wickedness, which spring from the vanity of the mind, and promise much liberty and pleasure, but deceive, and therefore lying; yea, all worldly enjoyments are vanity and vexation of spirit, and are fallacious and deceitful when trusted in; and indeed every false trust and confidence may come under this name; such as trust in riches, in wisdom and knowledge, in carnal descent, and privileges, in a moral and legal righteousness, and even in a bare profession of true religion, and a subjection to Gospel ordinances; for there is no true object of trust, no Redeemer and Saviour, but the Lord: now such as regard those lying vanities are they that look to them, love them, embrace them, and put their confidence in them; and such are to be "hated"; not their persons, but their principles and practices, and they themselves are to be shunned and abstained from;
but I trust in the Lord; the God of truth, that cannot lie, deny himself, nor deceive; who is unchangeable, and without any variableness, or shadow of turning.

Vanities - Idols, which are often called Vanities, as Deuteronomy 32:21. Or, curious arts, and all sorts of divinations.
