Matthew Henry, Matthew Henry's Commentary on the Whole Bible… (1700s)
“ Observe, When men have cast off fear and prayer their mouths utter iniquity. Those that cease to do good soon learn to do evil. What can we expect but all manner of iniquity from those that arm not themselves with the grace of God against it? But thou choosest the tongue of the crafty, that is, "Thou utterest thy iniquity with some show and pretence of piety, mixing some good words with the bad, as tradesmen do with their wares to help them off." The mouth of iniquity could not do so much mischief as it does without the tongue of the crafty. ”
