Thy vain thoughts - “Thy” iniquitous “thoughts.” “Aven,” the word used here, is especially applied to the sin of idolatry: thus Bethel is generally called Bethaven by Hosea (Hosea 4:15; Hosea 5:8, ...), because instead of being the house of God, El, it was the house of an iniquity, Aven, the golden calf.
