The king of Assyria carried the Israelites away to Assyria...because they did not obey the voice of YHWH their God but transgressed his covenant, even all that Moses the servant of YHWH commanded. They neither listened nor obeyed.
2 Kings 18:11-12

Sennacherib thought that he and his gods conquered the northern kingdom of Israel, but YHWH did. Nobody can defeat Israel unless they first undermine their relationship with YHWH, and then God will hand Israel over to her enemies.
