'Downfall' in the Bible

Now by the purpose of God, Ahaziah's journey to see Jehoram was the cause of his downfall: for when he came there, he went out with Jehoram against Jehu, the son of Nimshi, who had been marked out by the Lord for the destruction of the family of Ahab.

You say, See, I have overcome Edom; and your heart is lifted up with pride: now keep in your country; why do you make causes of trouble, putting yourself, and Judah with you, in danger of downfall?

For he made offerings to the gods of Damascus, who were attacking him, and said, Because the gods of the kings of Aram are giving them help, I will make offerings to them so that they may give me help. But they were the cause of his downfall, and of that of all Israel.
