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]Failure is never a pleasant feeling. It isn’t enjoyable to lose a job, see a relationship falter, or fail a test. But the disappointment we feel when we face defeat can be turned to joy if we look at it the right way!
A "beachhead" is the first objective, the primary location for a military force landing on an enemy shore, which, when secured can be used to gain further advancement.
This is the touching story of how Yeshua (Jesus) was anointed before His crucifixion. But there's one thing about this passaage that stood out to me as I read it again.
As the war continues in Israel, much has been made of the success of the Iron Dome defense system which shoots down incoming rockets from the Gaza Strip. While we are very thankful for the protection this system affords, it does present a certain public relations challenge for Israel. Somehow, regardless of the differences in both size and intention between Israel and the Arab world, the global media frequently emphasizes what they call, “moral equivalency”. The perception of Israel’s military strength and technical superiority somehow makes her the aggressor with an unfair advantage.
There is an important lesson here and in other places of God's Word, namely that humility and gladness go together. What do the humble and the joyous have in common? They both look up. The humble are those who don't look down on anyone. The truly humble look up all the time. They have to look up, because their eyes are on God, and He's above them. The joyous are always looking up as well, otherwise they wouldn't be rejoicing. The joyous are believing the Good News, so they rejoice!
Picture this — you come home from a long day of work — you walk into your living room — plop down on your couch in exhaustion — and there in the corner of the room — your eyes are drawn to something moving — it’s a rattlesnake! Do you say to yourself, “Oh, I’m too tired to worry about that now, I’ll deal with it later?” Of course not! You’d jump up right away, find a bat or something of the like, alert your family, call the neighbors, call 911, call the fire department and who knows what else! It’s a life-threatening situation!
Have you ever heard of the Valley of Elah? It's the valley near Bet Shemesh where David defeated Goliath, yet this historic battlefield is virtually untouched in Israel. During the rainy season a brook runs through the midst of the valley, however it dries up during the summer. This brook is very likely the one from which David chose his five smooth stones – one of which was used to kill Goliath. Yet, this historic place has no landmarks, no churches – people drive past it all the time unaware of it's biblical or historic significance.
