All their evil appears at Gilgal: Gilgal was the base camp for Joshua’s army (Joshua 5:10; 10:6, 43) and the place where Saul became king (1 Samuel 11:15). Saul also disobeyed God and was rejected as king at Gilgal (1 Samuel 13:8–15; 15:10–23). Israel’s leaders, including its first king, led the nation away from their true king, the Lord.
I will no longer love them: Although a different Hebrew word is used here, the prophetic judgment reflects the name of Hosea’s daughter (Hosea 1:6).
