Isaiah 36:1

Now, it came to pass in the fourteenth year of King Hezekiah that Sennacherib, king of Assyria, came up against all the defensed cities of Judah, all those which were fortified with walls and towers, and took them, their number, according to an Assyrian account of the expedition, being forty-six. The Assyrian attack was directed primarily against Phoenicia, Philistia, Edom, and Moab, but the enemies also overran the country of Judah.
