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]Yesterday marked the 1st day of Nissan, the beginning of the year on the Hebrew calendar. Nissan is known as the “month of miracles”, derived from the Hebrew word, “nissim”, which means “miracles”. Israel finally and miraculously left Egypt in the month of Nissan after hundreds of years of slavery. God orchestrated their escape, “nus” in Hebrew, (which some say is connected to Nissan), displaying His power over the Egyptian gods and His sovereignty over every pantheon. Nissan may also be related to the Hebrew word “nitzan”, which means “to bud” or “to start fresh and anew”, reflecting the seasonal advent of new life and new beginnings…springtime.
This is a powerful passage which believers must claim! The Greek for the word “heaven”, “oo-ran-os”, implies not only heaven, but also eternity. The enemy was removed from the eternal places, and his power is only temporary in this world. Our power does not come from this temporary world, but from eternity, from the eternal throne of God.
Over the last week, tensions have escalated significantly following the assassination of an Iranian General and several terrorist leaders within the Iranian Embassy compound in Damascus. This week also coincides with the conclusion of Ramadan, during which there have been heightened calls from terrorist groups for attacks against Jewish and Christian communities. The war drums are beating … and the question is — how should we as believers respond?
An official of a mission board, who knew it takes more than just desire to make a missionary, was appointed to examine a candidate for the mission field. He told the young man to be at his house at six o’clock in the morning. The young man complied and arrived a six o’clock sharp. The examiner kept him sitting alone in the room until ten…
The Bible speaks of a great falling away in the last days (2 Thessalonians 2) before the end of the age arrives, and it seems that we’re seeing it on a grand scale all around us. Virtually everywhere we look we’re watching the decline of morality and ethics — in government, entertainment, and social culture. It seems hard to deny…
Continuing our study on prayer I want to emphasize the confidence we can have as we approach the Lord. The exact moment we move toward Him to pray, we are exercising faith….which immediately pleases Him. He knows that we need His mercy and grace, and because He constantly intercedes on our behalf, we can be assured He will hear us and respond. Our approach is not based on our own merits, but on His righteousness and mercy. Having been tempted at all points as we are [Hebrews 4:15], His identification and understanding enable us to approach His presence with bold confidence.
One of the most important aspects of prayer is understanding how God Himself is interceding for us in ways we cannot fathom or comprehend. While Yeshua’s (Jesus) atonement was completed on the cross 2000 years ago, His continuing work of intercession rests soundly on the basis of it. He now lives … to make intercession for us! As our Lord is the same yesterday, today and forever [Hebrews 13:8], He is “faithful and true” and will always intercede according to the Father’s will, both in personal, individual matters, and also as we take up battles in prayer for others, including every arena of spiritual warfare.
