21 And all the people of Judah took Azariah, who was sixteen years old, and made him king in the room of his father Amaziah.

Matthew Henry's Commentary on 2 Kings 14:21

Commentary on 2 Kings 14:15-22

(Read 2 Kings 14:15-22)

Amaziah survived his conqueror fifteen years. He was slain by his own subjects. Azariah, or Uzziah, seems to have been very young when his father was slain. Though the years of his reign are reckoned from that event, he was not fully made king till eleven years afterwards.
