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 Psalms 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.
