2 Chronicles 26:2

All the people of Judah took Uzziah, who was sixteen years old, and made him king in the place of his father Amaziah.

Uzziah was sixteen years old when he began to reign; and he reigned fifty-two years in Jerusalem. His mother’s name was Jechiliah, of Jerusalem.

He did that which was right in the LORD’s eyes, according to all that his father Amaziah had done.

He set himself to seek God in the days of Zechariah, who had understanding in the vision of God; and as long as he sought the LORD, God made him prosper.
