1 Kings 15:14

14. But the high places were not removed That is, the high places, like those of 1 Kings 3:2, where Jehovah, and not idols, was worshipped. According to 2 Chronicles 14:3, he took away the altars of the strange gods, and the high places of the same; but the temple worship had probably fallen into such disrepute during the reigns of Rehoboam and Abijam that large numbers of the people resorted to the practice so common before the temple was built, (see 1 Kings 3:2,) of sacrificing on high places. And this had now become so prevalent a practice that Asa could not effectually stop it.

Nevertheless Asa’s heart was perfect That is, he followed the commandments of God with his whole heart, and in that respect was like David, 1 Kings 14:8. The standard of perfection by which we are to measure the perfect ones of the Old Testament history is not the fulness of spiritual light and religious attainment which is set before us in the New Testament, but rather a singleness and earnestness of pious purpose to obey God and maintain the honour of his name.

All his days His earnest purpose to maintain the true worship of God doubtless continued all his days; but he was angry with the prophet, who reproved him for seeking help of the king of Syria rather than of Jehovah, and imprisoned him; and in his disease he sought aid of the physicians instead of the Lord. 2Ch 16:10 ; 2 Chronicles 16:12.
