3. The words of his mouth are iniquity and deceit. The two clauses of this verse may be understood as referring to the same thing, namely, that the wicked indulging in deceit and vanity, will not receive or admit the light of understanding. This, I apprehend, is the meaning of David. He reproves the wicked not merely for circumventing others by their wiles and stratagems, but especially because they are altogether destitute of uprightness and sincerity. We have already said that the Psalmist is here speaking not of sinful and wicked men, in whose hearts there still remains some fear of God, but of the profane despisers of his name, who have given themselves up entirely to the practice of sin. He therefore says that they have always in their mouth some frivolous excuses and vain pretexts, by which they encourage themselves in rejecting and scoffing at all sound doctrine. He then adds, that they purposely suppress in themselves all knowledge or understanding of the distinction between good and evil, because they have no desire to become better than they are. We know that God has given understanding to men to direct them to do what is good. Now David says that the wicked shun it, and strive to deprive themselves of it, that they may not be constrained to repent of their wickedness, and to amend their lives. We are taught from this passage, that if at any time we turn aside from the path of rectitude, the only remedy in such a case is to open the eyes of our understanding, that we may rightly distinguish between good and evil, and that thus we may be led back from our wandering. When, instead of doing this, a man refuses instruction, it is an indication that he is in a state of depravity altogether desperate.
