2 Kings 17:3-4

17:3 King Shalmaneser of Assyria threatened him; Hoshea became his subject and paid him tribute. 17:4 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.
