Psalms 36:3

The words of his mouth [are] iniquity and deceit: he hath left off to be wise, [and] to do good.

Ver. 3. The words of his mouth are iniquity and deceit] That is, saith Calvin, he hath something to say to excuse and justify himself, to the hardening of his heart and hastening of his destruction; and there is no wool so coarse but will take some colour. But God will one day wash off his varnish with rivers of brimstone; he can skill of no other language but that of hell; the words of his mouth are, desiderium et dolus; there is no truth, and as little trust to be put in anything that he speaketh. And why? there is no fear of God before his eyes. See a like text, Romans 3:13,15 .

He hath left off to be wise, and to do good] That little light he once had he hath lost, and cast off such good practices as once in hypocrisy he performed; neither will he learn to do better. Dicit reprobos fugitare rationem bene agendi, ne vitam suam in melius corrigere cogantur, saith Vatablus.
