'Downfall' in the Bible

Ahaziah’s downfall came from God when he went to Joram. When Ahaziah arrived, he went out with Joram to meet Jehu son of Nimshi, whom the Lord had anointed to destroy the house of Ahab.

He sacrificed to the gods of Damascus which had defeated him; he said, “Since the gods of the kings of Aram are helping them, I will sacrifice to them so that they will help me.” But they were the downfall of him and of all Israel.
