Isaiah 31

1
Woe to those who go down to Egypt for help, and rely on horses, and trust in chariots because they are many, and in horsemen because they are very strong, but they don’t look to the Holy One of Israel, and they don’t seek the LORD!
2
Yet he also is wise, and will bring disaster, and will not call back his words, but will arise against the house of the evildoers, and against the help of those who work iniquity.
3
Now the Egyptians are men, and not God; and their horses flesh, and not spirit. When the LORD stretches out his hand, both he who helps shall stumble, and he who is helped shall fall, and they all shall be consumed together.
4
For the LORD says to me, “As the lion and the young lion growling over his prey, if a multitude of shepherds is called together against him, will not be dismayed at their voice, nor abase himself for their noise, so the LORD of Armies will come down to fight on Mount Zion and on its heights.
5
As birds hovering, so the LORD of Armies will protect Jerusalem. He will protect and deliver it. He will pass over and preserve it.”
6
Return to him from whom you have deeply revolted, children of Israel.
7
For in that day everyone shall cast away his idols of silver and his idols of gold—sin which your own hands have made for you.
8
“The Assyrian will fall by the sword, not of man; and the sword, not of mankind, shall devour him. He will flee from the sword, and his young men will become subject to forced labor.
9
His rock will pass away by reason of terror, and his princes will be afraid of the banner,” says the LORD, whose fire is in Zion, and his furnace in Jerusalem.
Chapter overviewAI-generated

Overview. This chapter pronounces judgment on those who seek military alliance with Egypt rather than trusting in the Lord, affirming that human strength—especially in horses and chariots—is futile against divine purpose. It contrasts the weakness of human alliances with the sure protection of the Lord, who will defend Jerusalem as a lion defends its prey and as birds hover over their young. The call is issued for Israel to repent and abandon idolatry, with the promise that Assyria will fall not by human hand but by divine judgment.

Flow.

  • The chapter opens with a woe against those who seek Egypt’s help, trusting in military might rather than seeking the Lord (v. 1).
  • God declares His sovereign wisdom and intent to bring disaster on the wicked, emphasizing that Egypt and its cavalry are mortal and powerless before His holiness (vv. 2–3).
  • A dual image of God’s unstoppable defense—like a lion unafraid of shepherds and like birds hovering over their nest—shows His commitment to protect Zion (vv. 4–5).
  • The call to repentance follows, urging Israel to return to God and forsake idolatry, culminating in the prophecy of Assyria’s divine overthrow (vv. 6–9).

Connections. Following chapter 30, which similarly condemns reliance on Egypt and promises God’s judgment and eventual restoration, this chapter deepens the contrast between human alliances and divine deliverance. Both chapters emphasize the futility of fleeing to Egypt instead of to God. The call to repentance in 31:6 directly prepares for chapter 32, which describes the coming of a righteous king and the outpouring of the Spirit, showing that true security comes not from political strategy but from God’s rule and renewal.

What it teaches. True safety lies not in military strength or foreign alliances but in seeking the Lord, who alone is sovereign and holy (WCF 3.7; HC LD 10). Human instruments, even powerful ones like Egypt’s cavalry, are mere flesh and cannot stand before the Spirit (WCF 4.1; BC Article 13). God’s defense of His people is both fierce and tender—like a lion and like hovering birds—demonstrating His omnipotent care (WCF 10.1; LC Q.74). Repentance is required of those who have turned from Him to idols, and He alone overthrows the proud powers of the world, as Assyria will fall not by human sword but by divine judgment (WCF 15.1; CD II.2). The fire in Zion symbolizes God’s holy presence, confirming His covenant commitment to redeem and dwell with His people (WCF 7.6; BC Article 21).

Apply. Trust in the Lord alone for deliverance, recognizing that no human power can substitute for His protection.
