Asa, the son of Abijah and grandson of Rehoboam, was the third king of Judah. He was a righteous man who maintained a true worship of God and did a lot to root out idolatry from the land.
Asa did what was right in the eyes of the LORD, as his father David had done. He expelled the male shrine prostitutes from the land and got rid of all the idols his fathers had made. He even deposed his grandmother Maacah from her position as queen mother, because she had made a repulsive Asherah pole. Asa cut the pole down and burned it in the Kidron Valley. Although he did not remove the high places, Asa's heart was fully committed to the LORD all his life.
(1 Kings 15:8-14)
In his old age, however, when afflicted with illness, he sought out the help of physicians rather than help from God.
He died after ruling for 41 years, greatly honored by his people. He was succeeded by his son Jehoshaphat.
