2 Kings 18:6-10

For he clave to the LORD, and departed not from following him, but kept his commandments, which the LORD commanded Moses.

And the LORD was with him; and he prospered whithersoever he went forth: and he rebelled against the king of Assyria, and served him not.

He smote the Philistines, even unto Gaza, and the borders thereof, from the tower of the watchmen to the fenced city.

And it came to pass in the fourth year of king Hezekiah, which was the seventh year of Hoshea son of Elah king of Israel, that Shalmaneser king of Assyria came up against Samaria, and besieged it.

And at the end of three years they took it: even in the sixth year of Hezekiah, that is the ninth year of Hoshea king of Israel, Samaria was taken.
