Baasha king of Israel went up against Judah and fortified Ramah to prevent anyone from leaving or entering the territory of Asa king of Judah. Asa then took the silver and gold out of the treasuries of the LORD's temple and of his own palace and sent it to Ben-Hadad king of Aram, who was ruling in Damascus. "Let there be a treaty between me and you," he said, "as there was between my father and your father. See, I am sending you silver and gold. Now break your treaty with Baasha king of Israel so he will withdraw from me." Ben-Hadad agreed with King Asa and sent the commanders of his forces against the towns of Israel. They conquered Ijon, Dan, Abel Maim [a] and all the store cities of Naphtali. When Baasha heard this, he stopped building Ramah and abandoned his work. Then King Asa brought all the men of Judah, and they carried away from Ramah the stones and timber Baasha had been using. With them he built up Geba and Mizpah. At that time Hanani the seer came to Asa king of Judah and said to him: "Because you relied on the king of Aram and not on the LORD your God, the army of the king of Aram has escaped from your hand. Were not the Cushites [b] and Libyans a mighty army with great numbers of chariots and horsemen ? Yet when you relied on the LORD, he delivered them into your hand. For the eyes of the LORD range throughout the earth to strengthen those whose hearts are fully committed to him. You have done a foolish thing, and from now on you will be at war." Asa was angry with the seer because of this; he was so enraged that he put him in prison. At the same time Asa brutally oppressed some of the people.

You may not know this but Asa hadn't fought a war in 32 years. That's probably why he didn't call on God. But, how could you forget about a war like that?
Then in the forty-first year of his reign Asa died and rested with his fathers.
