41In the fourth year of Ahab’s reign over Israel, Jehoshaphat son of Asa became king of Judah. 42Jehoshaphat was thirty-five years old when he became king, and he reigned in Jerusalem twenty-five years. His mother’s name was Azubah daughter of Shilhi. 43And Jehoshaphat walked in all the ways of his father Asa; he did not turn away from them, but did what was right in the eyes of the LORD. 44The high places, however, were not removed; the people still sacrificed and burned incense on the high places. Jehoshaphat also made peace with the king of Israel. 45As for the rest of the acts of Jehoshaphat, along with the might he exercised and how he waged war, are they not written in the Book of the Chronicles of the Kings of Judah? 46He banished from the land the male shrine prostitutes who remained from the days of his father Asa. 47And there was no king in Edom; a deputy served as king. 48Jehoshaphat built ships of Tarshish to go to Ophir for gold, but they never set sail, because they were wrecked at Ezion-geber. 49At that time Ahaziah son of Ahab said to Jehoshaphat, “Let my servants sail with your servants,” but Jehoshaphat refused. 50And Jehoshaphat rested with his fathers and was buried with them in the city of his father David. And his son Jehoram reigned in his place.
