1 Kings 15:14

But the high places were not removed: nevertheless Asa's heart was perfect with the LORD all his days.

But the high places were not removed,.... That is, such as had been used for the worship of God, before the temple was built, which yet now should have been removed, since sacrifice was now only to be offered there; but he might think they were still lawful, or the people had such an opinion of them, that it was difficult and dangerous to attempt to remove them; otherwise high places for idolatry were removed by him, 2 Chronicles 14:3,

nevertheless, Asa's heart was perfect all his days; he was sincere in the worship of God, and did everything to the best of his knowledge and capacity for restoring true religion, and destroying idolatry.
