Psalms 31:6

“In the morning it flourisheth and groweth up, etc.] That is, the grass, through the dew that lay all night on it, and by the clear shining of the sun after rain, when it appears in great beauty and verdure; so man in the morning of his youth looks gay and beautiful, grows in the stature and strength of his body, and in the endowments of his mind; and it may be also in riches and wealth; it is well if he grows in grace, and in the knowledge of Christ: in the evening it is cut down, and withereth; the Targum adds, “through heat”; but it cannot be by the heat of the sun, when it is cut down at evening; but it withers in course, being cut down. This respects the latter part of life, the evening…”

“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.…”

“Vanities - Idols, which are often called Vanities, as Deu 32:21. Or, curious arts, and all sorts of divinations. Psalms 31:7”

“31:6-8 Trust in the Lord requires confidence that he has our best interests at heart.”
