2 Kings 13:10

In the thirty and seventh year of Joash king (g) of Judah began Jehoash the son of Jehoahaz to reign over Israel in Samaria, [and reigned] sixteen years.

(g) His chief purpose is to describe the kingdom of Judah, and how God performed his promise made to the house of David: but in the process he shows how Israel was afflicted and punished for their great idolatry, who though they had now degenerated, yet God both by sending them many prophets and various punishments, called them to him again.
