Much like Isaiah 3:1-26, Isaiah 5:1-30 directly describes and confronts the rampant sin of the Jewish People while vindicating the impending doom of divine wrath. God would have the people know the just plans of divine anger, here called “Captivity” (Isa. 5:13) for the first time in the Book of Isaiah. Thus far in Isaiah these prophetic indictments are descriptive of the Kingdom of Judah during Uzziah’s reign after his apostasy and before his death, as his death is recorded in Isaiah 6:1. Also, understandably so, the foretold “Captivity” being spoken of in Isaiah 5:13 speaks primarily of the Assyrian Captivities, as is directly identified by the prophet in Isaiah 6:11-13, 7:17-25, 8:1-8, 10:5-15, & 10:28-34. My reader, this historical context pervades the ongoing prophecies in Isaiah 5-10. However, in the latter portion of Isaiah 5, specifically in verses 26-30, the prophecy veers into another dimension to unveil the Celestial Army that is the real power behind the Terrestrial Armies of Assyria. However, this revelation indicates a judgment of God far worse than the likes of historical Assyria, as & do alarmingly declare in Revelation 9:1-19.
In accordance with this greater scope of prophecy, Isaiah hears of God’s Glory as it will exist in the Millennial Reign of Christ (“the whole earth is full of His glory” - Isa. 6:3), as it will be accomplished by the virgin-birth incarnation of “Immanuel” (Isa. 7:14), “the Branch” (Isa. 4:2), the same One also called “the Light” (Isa. 9:2), whose acts are described in Isaiah 9:6-7 in no uncertain terms. Albeit, to the astonishment of the ancient observers of these prophecies (those who lived through the Assyrian Captivities), it became evident that these prophecies transcended the historical situation herein contextualized. Indeed, the first yet-to-be-born child (one of a three-part series of signs and wonders according to Isaiah 8:18) foretold in this prophecy does marvelously transcend history even though God was directly speaking to wicked King Ahaz in reference to the confederacy being made between Syria and Israel (Isa. 7:1-16). Meanwhile, Isaiah’s two children are entirely historical, their names being Shear-jashub (Isa. 7:3, 10:20-22) and Maher-shalal-hash-baz (Isa. 8:1-4). Note: see in Isa. 10:16-19.
