Abijah dies and his son Asa reigns in his place. In his days the land has rest for ten years. Asa does what is good and right in the eyes of the Lord his God. He removes the foreign altars and the high places, breaks down the pillars and cuts down the Asherim. He commands Judah to seek the Lord, the God of their fathers, and to obey the law and the commandment. He also removes from all the cities of Judah the high places and the incense altars, and the kingdom has peace under him.
Asa builds fortified cities in Judah, because the land has rest and there is no war against him in those years, for the Lord gives him rest. He tells Judah to build walls, towers, gates and bars while the land is still before them, because they have sought the Lord their God and he has given them rest on every side. They build and prosper. Asa has an army of three hundred thousand men from Judah armed with large shields and spears, and two hundred eighty thousand from Benjamin with small shields and bows.
Zerah the Cushite marches out against them with an army of a million men and three hundred chariots, and comes as far as Mareshah. Asa goes out to meet him, and they draw up in the Valley of Zephathah near Mareshah. Asa cries out to the Lord, saying that for him there is no difference between helping the mighty and those who have no strength, and asks for help because they rely on him and in his name have come against this multitude. The Lord defeats the Cushites before Asa and Judah, and they flee. Asa and his army pursue them as far as Gerar, and so many Cushites fall that they cannot recover. Judah takes great plunder from the cities around Gerar, for the fear of the Lord had fallen on them, and also tents of livestock and many camels and sheep, and they return to Jerusalem.
