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]Yeshua (Jesus) is the Prince of Peace (Sar Shalom, in Hebrew). You may have already known that the word "shalom" means peace. But actually, it has several meanings in the Hebrew. Shalom means peace, completeness, prosperity, safety, contentment, health, blessing, and rest -- and not only that. Shalom is the common word for hello and goodbye.
Simeon must have been a remarkable man, one who continued to seek God all his life. The Lord rewarded him by finally revealing to him the infant Yeshua's identity as Messiah of Israel and Savior of the world, and allowing Simeon to actually hold and bless the "lamb of God".
When Paul wrote to the Philippian church he spoke of pressing forward for the prize of the high calling. Though he was physically content whether rich or poor, [Philippians 4:11] the apostle was not content with his spiritual condition, but constantly seeking a deeper, more intimate and fruitful walk with the Lord...
There is a process going on in us believers. Since the day the Holy Spirit came to dwell in us He has been at work with perfect wisdom and supernatural power to renew and transform our character, to some extent, our personality, and even our physical body. Our outward man, this mortal body with it’s natural weakness and sinful ways was doomed to death and is “wasting away” even now.
As parents trying to raise kids in this world, we’re constantly reminded by the Lord of Proverbs 22:6, ‘Train up a child in the way he should go: and when he is old, he will not depart from it.’ The Hebrew word ‘train’, in this passage is, ‘Chanak’ which can be translated, ‘train up’ or ‘dedicate.’ It’s the root word from which we get the word, Chanukah.
Some time ago, we wrote about pearl harvesting as an illustration of how the Lord takes us into His “shell” like an irritating grain of sand, and over time, covers us with His beautiful covering, forming us into polished and precious gems for his glory and delight. This image of sanctification takes the metaphor in one direction: but here is another interesting thought. The beautiful pearl inside the oyster cannot be seen or enjoyed without a great price being paid. The oyster must die. It must be torn open in order to find the treasure within. This speaks to me of the original foundation and source of our beauty. Yeshua (Jesus) our Messiah had to be bruised, afflicted, torn and killed so that the beautiful treasures God intended us to be from the beginning, could be discovered and released from the darkness of sin.
Lately we’ve been receiving more and more calls and emails asking us what we think might happen in the near future and how they should prepare. I love what John Calvin had to say about the matter…
