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 parable in Matthew 25 is a warning to the entire body — be ready with your oil! Each of these virgins was anticipating the Lord’s return; none were atheists, or non-believers. They were all virgins who claimed to be awaiting the Bridegroom’s arrival. But notice carefully that only half of them were truly ready.
In the year 1920, young Oswald Smith stood before the examining board for the selection of missionaries. He had wanted to be a missionary for as long as he could remember, and for all that time had been crying out to God that He might open a door for him to do so. Finally, his time had come. There he stood awaiting his destiny. His long-awaited was about to come…”No.”
When God called Gideon to lead Israel against their enemies, He wanted to show that a small army empowered by God was more effective than the largest armies. But notice how they fought – without weapons that an army would normally use. They fought with shofars and lamps! They fought with weapons that the world would consider ineffective, yet triumphed mightily over their enemies. They shouted as loud as they could, sounded the shofar, and broke the vessels that held the fire so that their lamps burst through with brightness.
Let me tell you a funny little story. An old mountaineer and his wife were sitting by the fireplace one evening, passing the time in silence. After a while, the wife broke the stillness and said, “Jed, I think it’s raining. Go outside and check, will ya?”
During his reign, King Frederick William III of Prussia found himself in a bind. Wars had been costly, and in trying to build the nation, he was seriously short of finances. After careful reflection, he decided to ask the women of Prussia if they would bring their jewelry of gold and silver to be melted down for their country. Each piece of jewelry he received, he would exchange for a decoration of bronze or iron as a symbol of his gratitude. These decorations would be inscribed, ‘I gave gold for iron, 18l3’.
In connection with the Hebrew Word “Amen”, meaning “faith”, “truth”, “belief”, and “trust”, consider this revealing passage in Isaiah which further amplifies the dimensions of the word in the most wonderful and comforting promise:
“He who blesses himself in the earth shall bless himself in the God of truth [“Amen” in Hebrew]. …
After spending forty years in the wilderness, the children of Israel crossed into the Promised Land arriving to immediately face what seemed an impregnable fortress and an impossible task. Imagine receiving the instruction to march around the fortified city seven times, then finally be commanded to shout with all your might and sound shofars!
