1 Kings 22:43 (KJV)

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.

Now the rest of the acts of Jehoshaphat, and his might that he shewed, and how he warred, are they not written in the book of the chronicles of the kings of Judah?
