Isaiah 8:6-8

6“Because these people (Judah) have refused the gently flowing waters of Shiloah And rejoice in Rezin [the king of Aram] and Remaliah’s son [Pekah the king of Israel],

7Now therefore, listen carefully, the Lord is about to bring on them the waters of the [Euphrates] River, strong and abundant— The king of Assyria and all his glory; And it will rise over all its channels and canals and go far beyond its banks.

8Then it will sweep on into Judah; it will overflow and pass through [the hills], Reaching even to the neck [of which Jerusalem is the head], And its outstretched wings (the armies of Assyria) will fill the width of Your land, O Immanuel.
