Isaiah 8:3-9 AMP

3 And I approached [my wife] the prophetess, and when she had conceived and borne a son, the Lord said to me, Call his name Maher-shalal-hash-baz [as a continual reminder to the people of the prophecy],

4 For before the child knows how to say, My father or my mother, the riches of Damascus [Syria's capital] and the spoil of Samaria [Israel's capital] shall be carried away before the king of Assyria.

5 The Lord spoke to me yet again and said,

6 Because this people [Israel and Judah] have refused and despised the waters of Shiloah [Siloam, the only perennial fountain of Jerusalem, and symbolic of God's protection and sustaining power] that go gently, and rejoice in and with Rezin [the king of Syria] and Remaliah's son [Pekah the king of Israel],

7 Now therefore, behold, the Lord brings upon them the waters of the River [Euphrates], strong and many–even the king of Assyria and all the glory [of his gorgeous retinue]; and it will rise over all its channels, brooks, valleys, and canals and extend far beyond its banks; [Isa. 7:17.]

8 And it will sweep on into Judah; it will overflow and go over [the hills], reaching even [but only] to the neck [of which Jerusalem is the head], and the outstretched wings [of the armies of Assyria] shall fill the breadth of Your land, O Immanuel [Messiah, God is with us]! [Num. 14:9; Ps. 46:7.]

9 Make an uproar and be broken in pieces, O you peoples [rage, raise the war cry, do your worst, and be utterly dismayed]! Give ear, all you [our enemies] of far countries. Gird yourselves [for war], and be thrown into consternation! Gird yourselves, and be [utterly] dismayed!
