Isaiah 7:1-2

During the time that Ahaz son of Jotham, son of Uzziah, was king of Judah, King Rezin of Aram and King Pekah son of Remaliah of Israel attacked Jerusalem, but the attack sputtered out. When the Davidic government learned that Aram had joined forces with Ephraim (that is, Israel), Ahaz and his people were badly shaken. They shook like trees in the wind.
