Psalm 106:6
We have sinned with our fathers, we have committed iniquity, we have done wickedly.
We have sinned with our fathers,.... Sinned in their first father Adam; derived a corrupt nature from their immediate ancestors; sinned after the similitude of their transgressions; sinned after their example, in like manner as they did; guilty of the same gross enormities as they were: though sufficiently warned by the words of the prophets, and by punishments inflicted, they continued their sins, a constant series and course of them, and filled up the measure of their iniquities; they rose up in their stead an increase of sinful men, to augment the fierce anger of God, Numbers 32:14. And this the psalmist, in the name of the people of Israel, confesses, as it was his and their duty and interest so to do, Leviticus 26:40, and as we find it was usual with Old Testament saints, Jeremiah 3:25.
we have committed iniquity, we have done wickedly; this heap of words is used to denote not only the multitude of their sins, but the aggravated circumstances of them; that they had committed all manner of sins, not sins of ignorance, frailty, and infirmity only; but presumptuous sins, sins against light and knowledge, grace and mercy; sins against both tables of the law, against God and their neighbour; and these attended with many aggravations: all which a sensible sinner is ready to make a frank and ingenuous confession of, and forsake; and such an one finds mercy with a God pardoning iniquity, transgression, and sin: this form of confession is followed by Solomon and Daniel, 1 Kings 8:47.
