2 Kings 15:35-39

Only the high places were not eliminated; the people still sacrificed and burned incense on the high places. He built the upper gate of the house of the Lord.

Now as for the rest of the acts of Jotham which he did, are they not written in the Book of the Chronicles of the Kings of Judah?

In those days the Lord began to send Rezin the king of Aram and Pekah the son of Remaliah against Judah.

And Jotham lay down with his fathers, and he was buried with his fathers in the city of his father David; and his son Ahaz became king in his place.
