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]There’s nothing we can do to earn God’s love, however if we want to experience His blessings we need to observe the qualifications that He’s given us in His Word. Psalm 112 details a whole list of blessings, but the key to receiving them is verse 1.
Looking at the relationship between “love and affection” (“chiba” in Hebrew) and “obligation” (“chova” in Hebrew), we find another closely related word, “chaver”, one of the Hebrew words for “friend”. Friends are people with whom we share love and affection and also a sense of obligation. Our God and Father wants us to be His friends, to share love and affection with Him and to carry the sense of responsibility and obligation which friendship requires.
We are called to be servants, are we not? Well, what does a servant do? He (or she) carries out the will of his master. A servant doesn’t tell his master what to do — he performs whatever tasks the master requests of him. A servant doesn’t choose what days or times it’s most convenient to serve his master. A servant’s function is simply to follow and obey his master’s instructions. A servant does not develop a vision for the master either. The master is the one with the vision — and he wants his servants to be ready and available to carry out that vision and bring it to fruition.
Momentum is simply the force or speed of movement that carries an object to its final destination. If you want to break through, you need to have a certain amount of momentum. In order for a rocket to blast into space, it needs tremendous momentum to break the gravitational barrier – but with the enormous power of jet engines and rocket fuel the ship is propelled faster and faster till it breaks free of the earth’s gravitational pull.
“Break up your fallow ground.” In this context, the Lord is referring to breaking up the ground overrun with weeds and thorns creating a hardness to produce righteous fruit.
This passage in Isaiah contains a poetic play on words which is lost to any reader but one who understands Hebrew. A word for word translation runs something like this: “If not you will believe (lo ta-aminoo), surely not you will be established (lo te-amenoo).” The three letter Hebrew root – “aleph”- “mem”- “nun”, is the same in both words, and the Holy Spirit through the prophet Isaiah is clearly playing on this root to emphasize His point. The same root letters are also used in the spelling for the familiar word “Amen” which literally means “truthfully”.
David is called a “man after God’s own heart.” Considering that he lusted after his neighbor’s wife, committed adultery with her, and had her husband murdered, the Lord’s description of him is remarkable. How could a man who was convicted a murderer and an adulterer also be called one after God’s own heart?
