Isaiah 51:9 Awake, awake, put on strength, O arm of the LORD; awake, as in days of old, the generations of long ago. Was it not you who cut Rahab in pieces, who pierced the dragon?
Psalms 89:9-10 You rule the raging of the sea; when its waves rise, you still them. 10 You crushed Rahab like a carcass; you scattered your enemies with your mighty arm.
Isaiah’s words summon one of the most dramatic images of God’s saving power: the Z’roah — the Arm of the LORD — cutting Rahab in pieces and piercing the dragon.
Here, Rahab is not the woman of Jericho but a poetic name for Egypt (Psalm 87:4), often symbolizing arrogant nations and the dark spiritual powers behind them. In Hebrew poetry, Rahab also evokes the sea monster of chaos, a stand-in for the forces that oppose God’s order. To say the Arm “cut Rahab in pieces” is to recall how God shattered Egypt’s pride and broke the grip of the powers that enslaved His people.
The dragon, or serpent, is another layer of this imagery. Behind Pharaoh’s cruelty and Egypt’s gods was the same ancient serpent that slithered into Eden — the chaos-bringer, the deceiver, the enemy of God’s purposes. When the Arm of the LORD struck Egypt with plagues and split the Red Sea, it was not only Pharaoh who was defeated; it was the serpent himself who was pierced, exposed as powerless against the covenant God of Israel. The Exodus was more than political liberation — it was a cosmic showdown, and the Arm of God prevailed.
The cry “Awake, awake!” is not a suggestion that God has grown weary or inattentive. In Hebrew, “lavesh oz” — “put on strength” — means to clothe oneself for action, to rise up ready for battle. The exiles were invoking the Arm that once destroyed Rahab, pleading for Him to act again in their day. This was a declaration of faith: the God who pierces the dragon once will pierce him again.
Yet the Arm does not only strike; it saves. The same Arm that shattered Egypt also carried Israel safely through the sea, making a way where there was none. The battle was never for spectacle but for the flock’s safety. Every sword-thrust against the dragon clears a path for God’s people to walk in freedom. His piercing blow is always for the sake of deliverance.
Prophetically, this piercing of the dragon finds its ultimate fulfillment in Messiah Yeshua (Jesus). At the cross, the Arm of the LORD struck the serpent’s head, disarming principalities and powers (Colossians 2:14-15). In His resurrection, He proved that the dragon has no final claim over His people. Revelation picks up the same imagery, declaring the final defeat of the great dragon, Satan, who is cast down forever (Revelation 12:9; 20:10). The Arm that pierced in Egypt pierced again at Calvary — and will pierce once more at the end of the age.
For us today, Isaiah’s cry becomes our own. In seasons when chaos swirls and the enemy’s roar seems loud, we call upon the Arm of the LORD — not as if He were asleep, but as an act of faith that He will rise and act again. The dragon still snarls, but his fate is sealed. The Arm has already pierced him, and His victory is our inheritance.
The Arm that pierced the dragon is the very Arm stretched wide at the cross for you. Call upon Him, and remember that He has already given you authority to tread upon serpents and scorpions and over all the power of the enemy (Luke 10:18–19). He will carve a way for you through raging seas, opening a path where there seems to be no way. So stand firm — for the dragon’s roar is nothing more than the echo of his defeat, and his end is already sealed. The same Arm that cut Rahab in pieces, that split the waters, that crushed the serpent’s head, is the Arm that now holds you secure and will carry you all the way home!

[worthy_plugins_devotion_single_body]This pivotal passage of scripture, Isaiah 52 and continuing into Isaiah 53, profiles a suffering servant whom the nation of Israel would not recognize. The spiritual leaders of Yeshua’s (Jesus) day were blinded to the messianic passages which pointed to the messiah’s role as a humble servant and bearer of sins.
A recent study by researchers at the University of Pennsylvania and University of California Los Angeles wanted to find out, “if you had to choose between more time and more money, what would it be?” While they found most respondents answered, “more money”, they also found that those who preferred “more time” were generally happier! When I read this article, it reminded me of a story, that I’d like to share.
The Lord spoke to Moses, who led the children of Israel out of Egypt to be desperately cornered with the Red sea before them and Pharaoh’s chariots advancing upon them from behind. Overwhelmed with terror they cry out to Moses, “It would have been better for us to serve the Egyptians than to die in the desert!” Having just miraculously escaped from the miserable life of slavery, and only beginning their new life of freedom, the children of Israel were faced with the most dire threat to their existence.
Over the past few weeks, we’ve begun a series of devotions based on the Exodus wanderings of the Children of Israel, and their tragic mistakes which we can learn from and avoid. One powerful influence common to their failures was fear.
For the past two weeks we have examined lessons from the OT account of Israel’s Exodus from Egypt in hope of avoiding the errors and attitudes of the children of Israel. This week we will draw connections between the Exodus and the prophecies in the book of Revelation.
For the past two weeks we’ve been building life lessons derived from the Exodus wanderings and from Paul’s exhortations to the church in Corinth. Notice carefully that Paul says, “these were written for our admonition upon whom the ends of the ages have come”…
…that is, written for us today! – admonitions from Paul to learn lessons from the history of the children of Israel.
Paul exhorts the church at Corinth about grumbling and complaining. He reminds the believers of the judgments that befell the 10 spies who brought a bad report of the land – and were struck down by a plague, and terrible fate of Korah and those aligned with him that came against Moses and Aaron and were swallowed up by the ground under them.
