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]Once upon a time, there was a prince who received a very rare and beautiful bird. He named her Goldie and placed her in a lovely, 14K gold cage. But the poor creature was not impressed by the gold at all. She pleaded for her freedom but the prince loved her much too much to part with her. Still, she continued to beg. In final desperation, she asked that he at least allow her go to her relatives and tell them that, though captive, she was still alive.
I came across an old legend about three cowboys crossing the desert on horseback by night. Suddenly, as they reached a rocky spot, a voice came from heaven and commanded them: “Friends, pick up some pebbles, put them in your pockets and do not look at them till morning.” The men looked at each other in astonishment and began to do as they were told. The voice went on to promise that if they obeyed, they would be both glad and sad. The perplexed men put a few pebbles each in their pockets and went on their way.
This is a story relayed by Corrie Ten Boom, “It was Christmas, 1944. My sister, Betsie, had died. I was in a hospital barracks in Ravensbruck, a Nazi prison camp. Dark it was in my heart, and darkness was around me. There were Christmas trees in the street between the barracks. Dead bodies of prisoners had been thrown under the Christmas trees. I tried to talk to the people around me about Christmas, but they mocked and sneered. At last I kept quiet.
The baby that came into the world through the scenario above was named Ishmael. According to Islamic belief, it was Ishmael that was offered as a sacrifice by Abraham, and through him that they became the rightful inheritors of the promises of God. In other words, Ishmael was the seed through which Islam was born. Hmmm.
When Jim Burke became the head of a new products division at Johnson & Johnson, one of his first projects was the development of a children’s chest rub. The product failed miserably, and Burke expected that he would be fired. When he was called in to see the chairman of the board, however, he met a surprising reception. “Are you the one who just cost us all that money?” asked Robert Wood Johnson. “Well I just want to congratulate you. If you are making mistakes, that means you are taking risks, and we won’t grow unless you take risks!” Apparently, Mr. Johnson wasn’t joking! Years later, Johnson & Johnson remains one of the largest multi-national manufacturers of pharmaceutical, diagnostic, therapeutic, surgical, personal hygiene, baby and biotechnology products.
In her book, Let Me Be a Woman, Elizabeth Elliot records the story of a friend who had great difficulty accepting the looks God had given her. While everyone this girl knew had grown beautiful golden hair, hers was black. And while they were all still growing, she had stopped. She grew to be only about four feet ten inches tall.
“A young man enlisted, and was sent to his regiment. The first night he was in the barracks with about fifteen other young men, who passed the time playing cards and gambling. Before retiring, he fell on his knees and prayed, and they began to curse him and jeer at him and throw boots at him. So it went on the next night and the next, and finally the young man went and told the chaplain what had taken place, and asked what he should do. ‘Well,’ said the chaplain, ‘you are not at home now, and the other men have just as much right to the barracks as you have. It makes them mad to hear you pray, and the Lord will hear you just as well if you say your prayers in bed and don’t provoke them.’
