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!

As we celebrated Yom Teruah (Feast of Trumpets) and are in the midst of “Yamin Noraim” or the days of awe, the days between the Feast of Trumpets and Yom Kippur, it is the season of repentance.
This is the season that the shofar (rams horn) is blown to heed the call of warning to repent from our sins and be clean. The shofar’s unique sounding blast is a wake-up call to all who will hear.
After our very small wedding in Jerusalem, my wife and I planned to have the big ceremony she’d always dreamed of, in Havre De Grace, Maryland. Rivka had it planned it to the tee. It was an outdoor wedding next to the longest standing lighthouse on the east coast. We were going to wow our guests with an entrance by way of sailboat. Ten dancers with candles in glasses were to proceed my beautiful bride as I awaited her under our hand-crafted chuppa, lit by the sunset on the bay.
As we find ourselves in the midst of the Yamim Noraim (Days of Awe), our hearts are centered this week on repentance as we prepare for Yom Kippur, which is approaching this Friday. In this spirit, I want to share something I discovered while studying the Jewish roots of many of Yeshua’s (Jesus’) parables. I came across an insightful teaching from a Jewish Rabbi, which I believe holds a valuable lesson for us today.
Between Rosh HaShannah and Yom Kippur are ten days. These days are known as “Yamim Noraim”, “the Days of Awe” — or also translated, the “Awesome days”. In Judaism it has been long believed that these days seal your fate for the upcoming year — and also allude to your final destiny, concerning whether your name continues to be written in the Book of Life.
One of the major themes of Rosh Hashana is called Akedat Yitzchak, which means the Binding of Isaac. According to Jewish tradition, God told Abraham that the ram’s horn – otherwise known as a shofar – should be blown on Rosh Hashana to remind people of the sacrifice that God provided Himself when Abraham was about to offer Isaac on Mount Moriah.
On Wednesday this week, we will celebrate the Biblical festival of Yom Teruah (Feast of Trumpets) otherwise known as Rosh Ha Shana. What’s interesting about Rosh Ha Shana (the Jewish celebration of the New Year), is that it doesn’t fall on the first day of the first month. It falls on the first day of the seventh month! It’s difficult for outsiders to understand this concept, but it all makes sense if we study how the Jewish year begins and how God is outlining this age according to the Jewish feasts.
Rosh Hashanah traditionally marks the Jewish New Year. “Shanah” is a unique Hebrew word meaning “to repeat, revise, or go over again”. As we begin the new year, with fall, then winter, spring, and summer, we remember the cyclical pattern of time in God’s creation. The nature of life is to repeat itself — to continue in a cycle, marked by Rosh HaShannah — a New Year. Although time is moving in a direction toward a definite destiny determined by the Creator, it does so in cycles … truly, “what goes around comes around”.
