1 Kings 15:9-11

So in the twentieth year of Jeroboam king of Israel, Asa began to reign as king over Judah. He reigned forty-one years in Jerusalem. His [great-grand]mother was Maacah the daughter of Abishalom (Absalom). [1 Kin 15:2] Asa did what was right in the eyes of the LORD, as did his father (forefather) David.
