I have not sat with vain persons, neither will I go in with hypocrites.
Read Chapter 26
Augustine of Hippo
AD 430
4. "I have not sat with the council of vanity" (ver. 4). I have not chosen to give my heart to them who endeavour to provide, what is impossible, how they may be blessed in the enjoyment of things transitory. "And I will not enter in with them that work wickedly." And since this is the very cause of all wickedness, therefore I will not have my conscience hid, with them that work wickedly.

Some would restrain his words to idolaters: but this would make his declaration of little importance to Christians, as many would say the same, though they dare not say that they flee from wicked society. We must also banish all such thoughts as would destroy us. (Berthier)
David was inspired to speak the sentiments of his soul, and praise his own sincerity more than ordinary men may do. He instructs us to have no society with the conventicles of any false religion. (Worthington)
