Psalm 106:39
Thus were they defiled with their own works, and went a whoring with their own inventions.
Thus were they defiled with their own works,.... Not the land only, but they themselves also; or "with their works" {a}, with the works of the Heathen they learned, Ps 106:35, or rather with their own works, the works of the flesh, especially their shocking idolatries: sin is of a defiling nature; it has defiled all men, it defiles all of men, all the faculties of their souls, and all the members of their bodies; nor can anything truly and thoroughly cleanse from it but the blood of Christ: even men's works of righteousness are as filthy rags and defiling, and much more their evil works.
and went a whoring with their own inventions; after other gods; idolatry is often in Scripture signified by whoredom; the idolatry of Israel and Judah is represented by two harlots and their lewd practices, in Ezekiel 23:1 and hence the apostate church of Rome is compared to a whore, because of her idolatry, Revelation 17:1.
