2Kgs 14:1

“"In the second year of King Joash son of Ahaziah of Israel, King Amaziah son of Joash of Judah began to reign," who avenged the death of his father, but with moderation, so that he spared the life of the relatives of the conspirators according to the prescriptions of the Law and was careful that the punishment might not be too excessive for the authors of the crime. Therefore Amaziah was pious, as long as he had before his eyes his father's unhappy end, whose cause he could not ignore: offense against the true religion [of God]. However, when his reign began to be very prosperous, [Amaziah] rejected his fear of God which he had conceived after witnessing his father's punishment, and embraced foreign cults. In the second book of the Annals, the Scripture relating his victory against the Edomites confirms that this was the reason of his apostasy: "But Amaziah took courage, and led out his people, and went to the Valley of Salt and smote ten thousand men of Seir. The men of Judah captured another ten thousand alive and took them to the top of a rock, and all were enchained." And the text adds, "After Amaziah came from the slaughter of the Edomites, he brought the gods of the men of Seir, and set them up as his gods and worshiped them, making offerings to them."”
