Here is another alleged discrepancy: in 2 Chronicles 14 we are told that King Asa removed the high places:
And Asa did what was good and right in the eyes of the LORD his God. He took away the foreign altars and the high places and broke down the pillars and cut down the Asherim and commanded Judah to seek the LORD, the God of their fathers, and to keep the law and the commandment. He also took out of all the cities of Judah the high places and the incense altars. And the kingdom had rest under him. (2 Chronicles 14:2-5 ESV)
But in I Kings 15:14 we read:
But the high places were not taken away.
Bahr, Thenius, Bertheau, and others say that the high places dedicated to idols were destroyed; while those dedicated to Jehovah were allowed to remain, since his true servants, having been long accustomed to them, might have been grieved by their removal. Keil thinks that the second text merely implies that the king did not succeed in carrying out thoroughly his reforms. Rawlinson suggests that the above texts refer to different times; Asa, in the early part of his reign, putting down idolatry with a strong hand, but in his later years, when his character had deteriorated, allowing idol-worship to creep in again.
Again, any of these things seems possible. In my mind, leaving the high places of Yaweh in place would make the most sense in this case, but that’s only a guess.
