2 Kings 15:5, 32

The LORD struck the king, so that he was a leper to the day of his death. And he lived in a separate house, while Jotham the king’s son was over the household, judging the people of the land.

In the second year of Pekah the son of Remaliah king of Israel, Jotham the son of Uzziah king of Judah became king.
