The rest of the life and times of Amaziah is written in The Chronicles of the Kings of Judah.
At the last they cooked up a plot against Amaziah in Jerusalem and he had to flee to Lachish. But they tracked him down in Lachish and killed him there.
They brought him back on horseback and buried him in Jerusalem, with his ancestors in the City of David.
Azariah - he was only sixteen years old at the time - was the unanimous choice of the people of Judah to succeed his father Amaziah as king.
Following his father's death, he rebuilt and restored Elath to Judah.
In the fifteenth year of Amaziah son of Joash king of Judah, Jeroboam son of Jehoash became king of Israel in Samaria. He ruled for forty-one years.
As far as God was concerned he lived an evil life, never deviating an inch from all the sin of Jeroboam son of Nebat, who led Israel into a life of sin.
But he did restore the borders of Israel to Lebo Hamath in the far north and to the Dead Sea in the south, matching what God, the God of Israel, had pronounced through his servant Jonah son of Amittai, the prophet from Gath Hepher.
God was fully aware of the trouble in Israel, its bitterly hard times. No one was exempt, whether slave or citizen, and no hope of help anywhere was in sight.
But God wasn't yet ready to blot out the name of Israel from history, so he used Jeroboam son of Jehoash to save them.
The rest of the life and times of Jeroboam, his victories in battle and how he recovered for Israel both Damascus and Hamath which had belonged to Judah, these are all written in The Chronicles of the Kings of Israel.
