Historical Context of Isaiah 31 Prophecy
Isaiah 31 addresses Judah's diplomatic crisis during the Assyrian threat of 705–701 BC, when King Hezekiah sought military alliance with Egypt rather than relying on Yahweh [6]. The chapter opens with a woe oracle against those "who go down to Egypt for help, and rely on horses, who trust in chariots because they are many and in horsemen because they are very strong, but do not look to the Holy One of Israel or consult the LORD" (Isaiah 31:1) [1]. This condemnation echoes the prohibition in Deuteronomy 17:16 against multiplying horses and returning to Egypt, framing Judah's diplomacy as covenant violation [1].
The Assyrian Context
The historical backdrop is Sennacherib's western campaign. After Hezekiah initially attempted political and military solutions—including paying tribute to Assyria (2 Kings 18:13–16)—he turned to Egypt for support [6]. Isaiah's prophecy exposes the futility of this strategy: Egypt is dismissed as weak and unreliable, while Assyria's power is acknowledged but subordinated to Yahweh's sovereignty [4, 5]. The prophet contrasts human military strength with divine intervention, insisting that "the Egyptians are man, and not God, and their horses are flesh, and not spirit" (Isaiah 31:3) [1].
Structure and Theological Argument
The chapter divides into four movements. First, the woe oracle condemns reliance on Egypt (31:1–3) [7]. Second, two similes depict Yahweh's protection of Jerusalem: a lion guarding its prey and birds hovering protectively over their young (31:4–5) [3, 5]. Third, a call to repentance anticipates a future turning from idolatry (31:6–7) [7]. Fourth, the prophecy concludes with the fall of Assyria—not by human sword but by divine judgment (31:8–9) [5, 7].
Matthew Henry observes that this chapter "is an abridgment of the foregoing chapter," reiterating themes from Isaiah 30 about misplaced trust and the certainty of God's deliverance [7]. The cross-references to Isaiah 30:1 underscore the continuity: both chapters denounce "rebellious children" who "carry out a plan, but not mine" [2]. John Gill notes that the prophecy "assures the Jews of God's care and protection" while simultaneously calling them to repentance, holding together judgment and hope [4].
The historical fulfillment came when Sennacherib's army was decimated outside Jerusalem (Isaiah 37:36), vindicating Isaiah's insistence that Yahweh, not Egyptian cavalry, would secure Judah's survival [3].

The sin of those that trusted in Egypt, with the reasons of their trust, and not looking to the Lord, and seeking him, is declared in Isa 31:1 and their folly exposed in so doing; since the Lord is wise, powerful, and unchangeable, and the Egyptians frail and weak; so that the helper and the helped must fall before him, Isa 31:2 wh”
- Isaiah (Methodist/Wesleyan) “Adam Clarke on Isaiah 31 (introduction): The Jews again reproved for their confidence in Egypt, finely contrasted with their neglect of the power and protection of God, Isa 31:1-3. Deliverance and protection are, notwithstanding, promised, expressed by two similes; the first remarkably lofty and poetical, the latter singularly beautiful and tender, Isa 31:4, Isa 31:5. Exhortation to repentance, joined with the prediction of a more reformed period, Isa 31:6, Isa 31:7. This chapter concludes like the preceding, with a prophecy of the fall of Sennacherib, Isa 31:8, Isa 31:9.”
- Isaiah (Protestant academic) “Tyndale House on Isaiah 31:1: 31:1-3 Isaiah delivered another vision regarding Judah’s negotiations with Egypt, which probably took place in 705–701 BC. During that time, the conquering Assyrians were on the move, threatening Judah. At first, Hezekiah tried political and military means to avert being totally conquered (see 2 Kgs 18:13-16). 31:1 What sorrow: This is the fifth of the six woes (see study note on 28:1–33:24). • Looking to the Lord implies seeking his guidance with a worshipful attitude (see Deut 4:29; Ps 105:3-4).”

A woe to those who, when the Assyrian army invaded them, trusted to the Egyptians, and not to God, for succour (Isa 31:1-3). II. Assurance given of the care God would take of Jerusalem in that time of danger and distress (Isa 31:4, Isa 31:5). III. A call to repentance and reformation (Isa 31:6, Isa 31:7). IV. A prediction of the fall of the Assyrian army, and the fright which the Assyrian king should thereby be put into (Isa 31:8, Isa 31:9).”
