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!

In the 4th century lived a Christian named Telemachus, in a remote village, tending his garden, and spending much time in prayer. One day, he believed he heard the voice of God telling him to go to Rome, so he obeyed, setting out on foot. Some weeks later, weary from his journey, he arrived in Rome about the time of a great festival.
One of my heroes of the faith, Watchman Nee, once said something profound about entering the rest of God. He said, “Carnal Christians crave works; yet amid many labors, they are unable to maintain calm in their spirit. They cannot fulfill God’s orders quietly as can the spiritual believers… their hearts are governed by outward matters. Being “distracted with much serving” (Luke 10:40) is the characteristic of the work of any soulish believer. They have not yet entered the rest of God.”
Thousands are gathering in Washington D.C. today to pray for the inauguration of the new president of the United States. I know a number of people who will be there and I think it’s a good thing, but this reminds me of a story I heard once.
We arrived at the airport late Thursday night with our bags and our kiddos only to find out that our flight was canceled because of a freak accident — a tractor ran into the plane, of all things! So we repacked our ourselves tightly into a small rental car to make the two hour drive to get back home to Arad in the middle of the night. Our flight was postponed till Sunday.
The Hebrew letter mem, equivalent to our English letter “M,” has a fascinating characteristic: it has two forms. The “open mem” appears at the beginning or middle of a word, with a small opening in its design. The “closed mem,” however, is used exclusively as the final letter in a word, fully sealed in its appearance. This distinction is consistent throughout the Hebrew language—except for one extraordinary exception found in the Bible.
Yeshua (Jesus) gave a remarkable parenthetic instruction in the middle of His Olivet discourse on the time of His coming and the end of the age. While it is unlikely that He himself said this, He certainly inspired Matthew to insert, “..let the reader understand”, concerning this critical event prophesied by Daniel, the Abomination of Desolation. His exhortation intended us (the readers of Matthew’s gospel) to learn what this means.
In John Bunyan’s best-selling book, Pilgrim’s Progress, the central character, Christian, begins his journey leaving the city of Destruction and ventures on his way toward the Celestial City. Early on his journey, Christian decides to depart from the narrow path onto an easier one which leads him to the territory of Despair and its stronghold, Doubting Castle.
