C. F. Keil and Franz Delitzsch on 2 Kings 17:10

2Ki 17:10

They set up for themselves monuments and asherim on every high hill, etc., - a practice condemned in 1Ki 14:16, 1Ki 14:23, as early as the time of Jeroboam. In this description of their idolatry, the historian, however, had in his mind not only the ten tribes, but also Judah, as is evident from 2Ki 17:13, “Jehovah testified against Israel and Judah through His prophets,” and also from 2Ki 17:19.
