Isaiah 7:1-2

Now it came to pass in the days of Ahaz the son of Jotham, the son of Uzziah, king of Judah, that Rezin king of Aram (Syria) and Pekah the son of Remaliah, king of Israel, went up to Jerusalem to wage war against it, but they could not conquer it. When the house of David (Judah) was told, “Aram is allied with Ephraim (Israel),” the hearts of Ahaz and his people trembled as the trees of the forest tremble in the wind.
