Psalms 26:4

I have not sat, i.e. chosen or used to converse with them; for sitting is a posture of ease and of continuance. I have been so far from an approbation or imitation of their wicked courses, (wherewith mine enemies reproach me,) that I have avoided even their company; and if accidentally I came into it, yet I would not abide in it. With vain persons, i.e. with liars, or false and deceitful persons, as the next clause explains it. And vanity is very frequently put for falsehood or lying. Neither will I go in; into their company, or with design to join in their counsels or courses, as the same word is used, Joshua 23:7. And conversation is oft expressed by going out and coming in. With dissemblers, Heb. with such as hide themselves, covering their crafty and wicked designs with fair pretences. I abhor such persons and practices, though I am accused to be such a one.
