Asa means in the bible: 1st king of Judah. The history of his reign can be found in 1 Kgs. 15-16, and 2 Chr. 14-16. According to legend, his heart was always perfect. He raised his army to efficiency and tore away the Egyptian yoke. For more than 250 years, Egypt was not invaded again. To stop Baasha the king of Israel, he formed an alliance with Benhadad from Syria. Azariah, the prophet advised him to remove the Asherim and sun-images from high places. He also deposed Maachah, queen-mother, and to destroy her idol. A national assembly then invited people to sign a covenant seeking Jehovah.
