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]Winston Churchill exemplified integrity and respect in the face of opposition. During his last year in office, he attended an official ceremony. Several rows behind him two gentlemen began whispering. "That's Winston Churchill." "They say he is getting senile." "They say he should step aside and leave the running of the nation to more dynamic and capable men." When the ceremony was over, Churchill turned to the men and said, "Gentlemen, they also say he is ...
Historian Shelby Foote tells of a soldier who was wounded at the battle of Shiloh during the American Civil War and was ordered to go to the rear. The fighting was fierce and within minutes he returned to his commanding officer. "Captain, give me a gun!" he shouted. "This fight ain't got any rear!"
I recently arrived back in Israel last week, and upon my arrival, there were severe thunderstorms, something unusual for this time of year. In these thunderstorms, rivers are often created in the desert, and the highway road along the Dead Sea is often closed during this time. Last week, a few people died traveling along this road as its car was carried away by a flash flood. This reminded me of another incident in my own life.
Let's consider Daniel for a moment. Here is one of the great rulers of the Persian empire, in charge of the King's affairs and of the affairs of the entire government. If anyone is really busy -- it's Daniel! But in spite of all this responsibility, he makes it a point to set himself apart from the world and pray three times a day.
Tonight begins the feast of Purim, which celebrates the deliverance of the Jewish people from one of many of Satan's attempts to purge them from the world. Mordechai gave Esther a great challenge then, "and who knoweth whether thou art come to the kingdom for such a time as this?"
Life can get so hectic sometimes -- we often try to do too many things at once. But when our schedule gets that hectic, we need to start investing in some quality time with the Lord. The operating word here is "investing".
The first man was called "Ah-dom", we know him as "Adam". The word used for "man", as in "mankind", in Genesis 1, is also the same word – "Ah-dom". "Ah-dom" is rooted in the three Hebrew letters, aleph-dalet-mem, and one of the Hebrew words for earth is "Adamah", which contains the same three letters, however it ends with the Hebrew letter "hay". "Adamah" means "red earth", or "red clay", and this word points to the natural earth elements, the "earth dust" that composed Adam’s body, and the body of every human being since. "Man" is "ah-dom", in a very real sense, "clay".
