9 In the twentieth year of Jeroboam king of Israel, Asa became king over Judah. 10 And he reigned forty-one years in Jerusalem. His grandmother's name was Maachah the granddaughter of Abishalom. 11 Asa did what was right in the eyes of the Lord, as did his father David. 12 And he banished the perverted persons from the land, and removed all the idols that his fathers had made. 13 Also he removed Maachah his grandmother from being queen mother, because she had made an obscene image of Asherah. And Asa cut down her obscene image and burned it by the Brook Kidron. 14 But the high places were not removed. Nevertheless Asa's heart was loyal to the Lord all his days. 15 He also brought into the house of the Lord the things which his father had dedicated, and the things which he himself had dedicated: silver and gold and utensils.

Commentary on 1 Kings 15:9-24
(Read 1 Kings 15:9-24)
Asa did what was right in the eyes of the Lord. That is right indeed which is so in God's eyes. Asa's times were times of reformation. He removed that which was evil; there reformation begins, and a great deal he found to do. When Asa found idolatry in the court, he rooted it out thence. Reformation must begin at home. Asa honours and respects his mother; he loves her well, but he loves God better. Those that have power are happy when thus they have hearts to use it well. We must not only cease to do evil, but learn to do well; not only cast away the idols of our iniquity, but dedicate ourselves and our all to God's honour and glory. Asa was cordially devoted to the service of God, his sins not arising from presumption. But his league with Benhadad arose from unbelief. Even true believers find it hard, in times of urgent danger, to trust in the Lord with all their heart. Unbelief makes way for carnal policy, and thus for one sin after another. Unbelief has often led Christians to call in the help of the Lord's enemies in their contests with their brethren; and some who once shone brightly, have thus been covered with a dark cloud towards the end of their days.
