Psalms 14:4

Hatred of God and corruptness of life are the motive forces which produce persecution. Men who having no saving knowledge of divine things, enslave themselves to become workers of iniquity, have no heart to cry to the Lord for deliverance, but seek to amuse themselves with devouring the poor and despised people of God. It is hard bondage to be a "worker of iniquity;" a worker at the galleys, or in the mines of Siberia, is not more truly degraded and wretched; the toil is hard and the reward dreadful: those who have no knowledge choose such slavery, but those who are taught of God cry to be rescued from it. The same ignorance which keeps men bondsmen to evil, makes them hate the freeborn sons of God; hence they seek to eat them up "as they eat bread, " —daily, ravenously, as though it were an ordinary, usual, every-day matter to oppress the saints of God. As pikes in a pond, eat up little fish, as eagles prey on smaller birds, as wolves rend the sheep of the pasture, so sinners naturally and as a matter of course, persecute, malign, and mock the followers of the Lord Jesus. While thus preying, they forswear all praying, and in this act consistently, for how could they hope to be heard while their hands are full of blood?

Have all the workers of iniquity no knowledge? - Is there not one of them who takes this dreadful subject into consideration? To their deeply fallen state they add cruelty; they oppress and destroy the poor, without either interest or reason. Who eat up my people as they eat bread - Ye make them an easy and unresisting prey. They have no power to oppose you, and therefore you destroy them. That this is the meaning of the expression, is plain from the speech of Joshua and Caleb relative to the Canaanites. Num 14:9: “Neither fear ye the people or the land; for they are bread for us.” And call not upon the Lord - They have no defense, for they invoke not the Lord. They are all either atheists or idolaters.

Have all the workers of iniquity no knowledge? - literally, “Do they not know, all the workers of iniquity, eating my people, they eat bread; Jehovah they call not.” The several statements in this verse in confirmation of the fact of their depravity are: (a) that they have no knowledge of God; (b) that they find pleasure in the errors and imperfections of the people of God - sustaining themselves in their own wickedness by the fact that the professed friends of God are inconsistent in their lives; and (c) that they do not call on the name of the Lord, or that they offer no worship to him. The whole verse might have been, and should have been put in the form of a question. The first statement implied in the question is, that they have “no knowledge.” This can be regarded as a proof of guilt only (1) as they have opportunities of obtaining knowledge; (2) as they neglect to improve those opportunities, and remain in voluntary ignorance; and (3) as they do this from a design to practice wickedness. See this argument stated at length by the apostle Paul in Rom 1:19-28. Compare the note at that passage. This proof of human depravity is everywhere manifested still in the world - in the fact that men have the opportunities of gaining the knowledge of God if they chose to do it; in the fact that they voluntarily neglect those opportunities; and in the fact that the reason of this is that they love iniquity. Who eat up my people as they eat bread - They sustain themselves in their own course of life by the imperfections of the people of God. That is, they make use of their inconsistencies to confirm themselves in the belief that there is no God. […]
