Thomas Aquinas, on Ps 13:4

“Shall not all they know that work iniquity, who devour my people as they eat bread?”

“"Shall they not." Here he treats of the hope of liberation. And first he shows that the wicked do not have hope, because "shall they not know." Second he shows what this hope is, at "Who shall give from Zion." Concerning the first, he does two things. First he shows that they will not know this hope. Second he sets forth a sign, at "The counsel of the poor man." First he raises a question, and interposes within it the fault of the wicked, and speaks thus. I say that they are an open sepulchre, and that God is not in their hearts: but shall they not know that the Lord is in the just generation? As if to say: they ought to know this, and that the Lord is in it: Jer. 14: "You are in our midst, O Lord, and your holy name," etc. Ps. 21: "But you dwell in the holy place, the praise of Israel." Therefore the Lord is in him as in a temple. "And all who work iniquity," namely against God, "who devour my people as the food of bread," as regards neighbors, whom they devour by taking away their goods: Zech. 11: "Let each one devour the flesh of his neighbor": Mic. 3: "They have eaten the flesh of my people and have flayed the skin from them": Sir. 34: "The bread of the needy is the life of the poor man: he who defrauds him of it is a man of blood." "They have not called upon God," that is, they have no hope in God: Is. 59: "They have not called upon God." And it follows from this that they have no security: therefore he says, "There they trembled," etc. Prov. 28: "The wicked man flees when no one pursues": Job 15: "The sound of terror is always in his ears, and when there is peace, he always suspects ambush." But those who call upon God are saved: Joel 2: "All who call upon the name of the Lord shall be saved": Prov. 18: "The name of the Lord is a most strong tower." Therefore such men will not know that the Lord is in the just generation.”
