John Gill Commentary 2 Kings 14:2

"He was twenty and five years old when he began to reign; and he reigned twenty and nine years in Jerusalem: and his mother`s name was Jehoaddin of Jerusalem." — 2 Kings 14:2 (ASV)

He was twenty-five years old when he began to reign, and reigned twenty-nine years in Jerusalem. Fourteen years contemporary with Joash king of Israel, who reigned sixteen years (2 Kings 13:10), and fifteen after him (2 Kings 14:17). And his mother's name was Jehoaddan of Jerusalem, of whom we nowhere else read.
