How can 1 Kings say Asa's heart was perfect when the high places stayed and he paid Ben Hadad?

1 Kings puts the two side by side in one verse: "But the high places were not taken away. Nevertheless the heart of Asa was perfect with the LORD all his days" (15:14). Perfect is shalem, which Brown-Driver-Briggs gives as "complete, safe, at peace"; it is the word of Solomon's charge to the people, "Let your heart therefore be perfect with the LORD our God" (8:61), and of the verdict on Abijam (15:3). Of the silver and gold sent to Ben Hadad (15:18-20), 1 Kings says nothing good or bad. 2 Chronicles tells of Asa's reign too, in its own words. It keeps the same verdict: "the heart of Asa was perfect all his days" (2 Chronicles 15:17). It also tells that Hanani the seer came to Asa and said, "Because you have relied on the king of Syria, and have not relied on the LORD your God, therefore the army of the king of Syria has escaped out of your hand" (2 Chronicles 16:7), and "You have done foolishly in this; for from now on you will have wars" (2 Chronicles 16:9); "Asa was angry with the seer, and put him in the prison" (2 Chronicles 16:10). Of his feet it says, "yet in his disease he didn’t seek the LORD, but just the physicians" (2 Chronicles 16:12). Neither book explains how its verdict and what it tells fit together. Readers weigh these verses in different ways, and these notes don't choose.
