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]According to church history, the apostle Thomas, died in Calamina, a city in the East Indies. While there, Thomas had put a stop to the idolatry that was running rampant in the land. The idolatrous priest was not happy about this at all and accused him before their king. The king sentenced Thomas to death -- first to be tormented by red hot plates and then cast into a glowing furnace and burned. When the priest saw that the fire was not hurting him, he pierced Thomas' side with spears and javelins, and finally Thomas died.
A significant response to the current pandemic has been medical professionals in various places offering valuable advice on the role of diet toward building and increasing our body's immunity to viruses and disease in general. This kind of advice can be truly salutary, even life-saving. Yet the aphorism, "You are what you eat", though often heard, isn't always taken as seriously as we might...And that may contribute to unpleasant health consequences.
Missionaries Dick and Margaret Hillis found themselves caught in China during the Japanese invasion. The couple lived with their two children in the inland town of Shenkiu. The village was tense with fear, for every day brought terrifying reports of the Japanese advance. At the worst possible time, Dick developed appendicitis, and he knew his life depended on making the long journey to the hospital. On January 15, 1941, with deep foreboding, Margaret watched him leave.
As Joshua led the children of Israel into the promised land it seemed that God had given them an impossible assignment -- to conquer a foreign and hostile land with fortified cities and armies greater than their own. They had to go forth only on the basis of God's promise. They had to walk by faith and not by sight!
Over the weekend, the ministry lost a dear brother who suddenly died of a heart attack. In times of mourning, the realization dawned (once again) that this life is utterly fleeting ... a vapor in the wind ... and these frail human bodies in which we dwell are mortal dust. We are living in the land of the dead and dying, and only those of us who truly know and are known by the Messiah, upon our death, will enter the land of the truly living!
An ancient story in Church history tells of the apostle John. He would constantly repeat the words, "Little children, love one another." And his disciples became weary of the phrase. Finally, in his old age, as John was being carried to their assembly, the disciples asked him, "Why do you always repeat these same words?" "Because friends," John replied, "it is the Lord's commandment -- and if only this one were fulfilled, it would be enough."
The apostle John quotes Isaiah 53:1, saying to whom has the z’roah [arm] of the Lord been revealed? It’s a question that God answers throughout the rest of Isaiah 53, describing in detail the life of Yeshua (Jesus) and the ultimate price He would pay for the sins of the world.
