2 Chronicles 26:1, 3-4

All the people of Judah had crowned Amaziah’s sixteen-year-old son, Uzziah, as king in place of his father.

Uzziah was sixteen years old when he became king, and he reigned in Jerusalem fifty-two years. His mother was Jecoliah from Jerusalem. He did what was pleasing in the LORD’s sight, just as his father, Amaziah, had done.
