Psalms 10:7 - Joseph Benson’s Commentary on the Old and New Testaments

His mouth is full of cursing Of oaths and blasphemies against God; of reviling and execration of other men, especially of those that are good, and those that stand in his way, and hinder his wicked designs; and, perhaps, also of oaths and imprecations against himself, by which he endeavours to gain credit, and to make his neighbours secure, and so to make way for the deceit and fraud here next mentioned. He sticks at nothing that may serve his ends: for he makes no conscience of calling for one curse after another upon himself to confirm those promises which he never intends to keep, or to swear that which he knows is false, that by these impious means he may deceive those who rely on his word or oath. Under his tongue Under his fair and plausible speeches; is mischief Mischievous wickedness lies hid, and vanity, or iniquity, as the word און, aven, is often rendered, or injury; the vexation or oppression of other men, which he covers with these fair pretences.
