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]One of my favorite ministers of the Gospel is D.L. Moody. He tells a story about having heard Pastor Henry Varley once say that, “The world has yet to see what God will do with and for and through the man who is fully and wholly consecrated to Him.”
The Lord is quoted in this scripture in Matthew and it contains an important principle which I think we sometimes tend to overlook. Many believe and even teach that if someone acquires much material prosperity, then God has surely given them favor, and that if someone is undergoing extreme trial, it must be because they have sinned or that they lack faith. But the Lord says that the sun rises and the rain falls on both the righteous and the unrighteous alike. A life of good circumstances does not necessarily mean that God is with us. And likewise, a life of trial and suffering does not mean that God is not with us!
The African Impala (an African antelope) are amazing creatures that can jump to a height of over 10 feet and cover a distance greater than 30 feet. Yet Impalas can be kept in a zoo inside an enclosure with a simple 3 foot wall. Why? Impalas will not jump if they can’t see where their feet will land. Do we have something in common with these antelopes? Able to take great leaps of faith, but refusing to do it unless we can see where we’ll land?
An aging king woke up one day to the realization that should he drop dead, there would be no male in the royal family to take his place. He was the last male in the royal family in a culture where only a male could succeed to the throne – and he was aging. He decided that if he could not give birth to a male, he would adopt a son who then could take his place but he insisted that such an adopted son must be extraordinary in every sense of the word. So he launched a competition in his kingdom, open to all boys, no matter what their background. Ten boys made it to the very top.
For centuries in Ethiopia, there have lived a people we now know as the Falashas. They kept all sorts of Biblical traditions and call themselves Beta Yisrael (House of Israel). As experts began to study the matter, it became clear that these were descendants of the Jewish people who came to Africa in ancient times and intermarried. Unbeknownst to many, a percentage of them became believers in Jesus over the years. Jesus (or Yeshua, as they called Him) became a part of their identity as Jewish people. Many Falashan Jews worshipped Jesus as their Messiah and continued to practice Jewish tradition.
So often in our walks with the Lord, we become focused on what we can see, what we can hear and what we can sense in the physical realm. Like that young man, we focus on the enemy’s attacks around and about us. At times we can get so focused on our physical circumstances that we forget that the Lord has already provided for us the victory!
Why is it that some believers seem to go much deeper in their walk with God than others? I believe it has to do with a desire to pursue God and not to stop until they feel His very presence in their lives. These believers decide not to settle for anything less than a growing, vibrant relationship with God, and God honors that desire for those who seek it.
