The king of Assyria discovered that Hoshea was planning a revolt. Hoshea had sent messengers to King So of Egypt and had not sent his annual tribute to the king of Assyria. So the king of Assyria arrested him and imprisoned him.

In the fourth year of King Hezekiah’s reign (it was the seventh year of the reign of Israel’s King Hoshea, son of Elah), King Shalmaneser of Assyria marched up against Samaria and besieged it.
