Albert Barnes Commentary 1 Kings 22:43

"And he walked in all the way of Asa his father; He turned not aside from it, doing that which was right in the eyes of Jehovah: howbeit the high places were not taken away; the people still sacrificed and burnt incense in the high places." — 1 Kings 22:43 (ASV)

On the general piety of Asa, see the commentary above on 1 Kings 15:11–15. Jehoshaphat seems to have been a still better king, for he did not, like Asa, fall away in his old age (2 Chronicles 16:2–12).

The high places were not taken away. This seems to contradict 2 Chronicles 17:6. Probably the writer of Chronicles refers to the desire and intention of the monarch, while the author of Kings records the practical failure of his efforts.
