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!

An artist went searching the streets of New York City for a model to pose for a portrait he wanted to call -- 'The Prodigal'. One day was passing Central Park and saw an impoverished beggar lying on a bench and thought: 'He's perfect! That man would represent the prodigal son beautifully in my painting.' He asked the beggar if he would be willing to sit for his painting and he would gladly pay him for his time. Naturally, the beggar agreed.
"If our greatest need had been information, God would have sent us an educator. If our greatest need had been technology, God would have sent us a scientist. If our greatest need had been money, God would have sent us an economist. If our greatest need had been pleasure, God would have sent us an entertainer..... but our greatest need was forgiveness, so God sent us a Savior."
D. L. Moody told the story of a man who was crossing the Atlantic by ship. He was terribly sick and confined to his cabin. One night he heard the cry “Man overboard!” He felt that there was nothing he could do to help, but at second thought, he said to himself, “I guess I can at least put my lantern in the porthole.” He struggled to his feet and hung the light so it shined out into the darkness.
Chanukah, a time of celebration and rededication, began last Thursday night here in the Land and for Jewish people all over the globe. Those of us who are grafted in through the atoning work of Messiah, we who know God, have an opportunity to see the deeper significance in the Jewish holidays and are not only welcome but encouraged to celebrate as well!
"In the washroom of his London club, British newspaper publisher and politician William Beverbrook happened to meet Edward Heath, then a young member of Parliament, about whom Beverbrook had printed an insulting editorial a few days earlier. "My dear chap," said the publisher, embarrassed by the encounter. "I've been thinking it over, and I was wrong. Here and now, I wish to apologize." "Very well," grunted Heath. "But the next time, I wish you'd insult me in the washroom and apologize in your newspaper."
These first two scriptures are speaking of the same "Stone", the prophesied Messiah Yeshua (Jesus), the "head of the corner" or "rosh pina", in Hebrew. This stone is laid in Zion, a common synonym for Jerusalem, where mount Zion rests. The stone is "tried", that is, tested in every way that a stone can be; the stone is precious and excellent to be set as a sure, reliable, accurate, even everlasting foundation, and a stone which is prepared and set in place by God, Himself. Can you think of a "Stone" more perfect or beautiful than our Messiah?
Years ago, I heard an anointed missionary and personal friend speaking on the consequences of sin. He told a story about a pair of brothers he knew quite well.
