2 Kings 18:5 (KJV)

Now it came to pass in the third year of Hoshea son of Elah king of Israel, that Hezekiah the son of Ahaz king of Judah began to reign.

Twenty and five years old was he when he began to reign; and he reigned twenty and nine years in Jerusalem. His mother's name also was Abi, the daughter of Zachariah.

And he did that which was right in the sight of the LORD, according to all that David his father did.

He removed the high places, and brake the images, and cut down the groves, and brake in pieces the brasen serpent that Moses had made: for unto those days the children of Israel did burn incense to it: and he called it Nehushtan.

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 in the ninth year of Hoshea king of Israel, Samaria was taken.
