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]Some of the wealthiest individuals in the United States are real estate developers. They make their money by buying a piece of property that is terribly run down, seemingly useless, without any value to the naked eye and reforming it completely, making it look brand new! These businessmen are not as much interested in what is on the property as they are interested in the land it’s on!
A sailor who was shipwrecked on a desert island was captured by some of the natives of that island. They carried him off on their shoulders to their village, where he was sure he would end up being the main course. But instead, they put a crown on his head and made him king. He was enjoying all the attention he was receiving but was growing a little suspicious. He started making inquiries and discovered that their custom was to crown a stranger king for a year and at the end of that year the crowned king would be sent to a deserted island where he was allowed to starve to death.
With war drums beating even more intensely in Iran and Syria, we’ve received numerous phone calls and emails expressing their concerns — and understandably so! Nevertheless, even in this climate of anxiety, we are preparing to enter into Shabbat (the Hebrew word for Sabbath) this afternoon. And as we do, we are remembering again, the deep lesson of God’s entering into His rest following the six creation days.
This is one of my favorite promises in the Bible — that God turns mourning into dancing! He takes away the anguish of being clothed in sadness and replaces it with gladness. However, notice what God doesn’t do — simply stop your mourning and make it disappear. No, He transforms it…into joy!
As we discussed last week, the word for “sign” in ancient Hebrew is “oht”. It was used in Genesis to designate God’s covenant sign with Noah, (the rainbow). And we see now the same word again, in Exodus, identified with the deliverance of the Jewish people from the tenth plague, when the angel of death passed through all Egypt to strike the firstborn. Anyone under the “sign” of the blood was spared.
Yesterday we wrote about one of the greatest moves of God … the Moravian Revival. When the community was in complete disarray, Count Zinzendorf focused on how they could live together in love despite their differences. He called all the men together for an intense study of the Scriptures to focus on how Christian life in community was portrayed. These studies combined with intense prayer convinced many of the believers that they were called to live together in love and that their disunity and conflict were contrary to the clear calling of Scripture.
In the late 1800s, an awakening in South Africa led by Andrew Murray was a powerful move of God. Studying that revival yields essential insights concerning the events occurring now throughout the United States. As the spirit of God began to move in Cape Town, Murray compared the SA revival with past experiences of revivals in Europe. He decided that the intense “emotionalism” was a false experience of God and charged in to break up the meeting. Stepping out of the church, he encountered his father standing and weeping. His father rebuked Andrew, “How dare you stop something that I have prayed to happen for 30 years!”
