'Treachery' in the Bible

And Joram turned his hands, and fled, and said to Ahaziah, There is treachery, O Ahaziah.

But the king of Assyria discovered a conspiracy in Hoshea, who sent messengers to So, king of Egypt, and offered no tribute to the king of Assyria, as he had done year by year; therefore the king of Assyria arrested him and bound him in prison.
