Psalms 78:39

“Thus were they defiled with their own works, etc.] Not the land only, but they themselves also; or “with their works” f1532, with the works of the Heathen they learned, (<19A635>Psalm 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.

Job 7:7, Job 7:16; Jam 4:14 Psalms 78:40”
