2 Kings 17:4
And the king of Assyria found conspiracy in Hoshea: for he had sent messengers to So king of Egypt, and brought no present to the king of Assyria, as he had done year by year: therefore the king of Assyria shut him up, and bound him in prison.
Hoshea's conspiracy against Assyria and his imprisonment mark the beginning of the final Assyrian judgment upon the northern kingdom. About two years after Hezekiah's invitation to repent was rejected, Samaria was invested by the hosts of Assyria under Shalmaneser. In the siege that followed, multitudes perished miserably of hunger and disease as well as by the sword.
The city and the nation fell, and the broken remnant of the ten tribes was carried away captive and scattered in the provinces of the Assyrian realm.
