Adam Clarke on Hosea 4:15

Let not Judah offend - Israel was totally dissolute; Judah was not so. Here she is exhorted to maintain her integrity. If the former will go to what was once Beth-el, the house of God, now Beth-aven, the house of iniquity, because Jeroboam has set up his calves there, let not Judah imitate them. Gilgal was the place where the covenant of circumcision was renewed when the people passed over Jordan; but was rendered infamous by the worship of idols, after Jeroboam had set up his idolatry.
