1 Kings 22:40-44

So Ahab slept with his fathers; and Ahaziah his son reigned in his stead.

And Jehoshaphat the son of Asa began to reign over Judah in the fourth year of Ahab king of Israel.

Jehoshaphat was thirty and five years old when he began to reign; and he reigned twenty and five years in Jerusalem. And his mother’s name was Azubah the daughter of Shilhi.

And he walked in all the ways of Asa his father; he turned not aside from it, doing that which was right in the eyes of the LORD: nevertheless the high places were not taken away; for the people offered and burnt incense yet in the high places.

And Jehoshaphat made peace with the king of Israel.
