9In the fourth year of Hezekiah’s reign, which was the seventh year of the reign of Hoshea son of Elah over Israel, Shalmaneser king of Assyria marched against Samaria and besieged it.
10And at the end of three years, the Assyrians captured it. So Samaria was captured in the sixth year of Hezekiah, which was the ninth year of Hoshea king of Israel.
