Isaiah 58:11 And the LORD shall guide thee continually, and satisfy thy soul in drought, and make fat thy bones: and thou shalt be like a watered garden, and like a spring of water, whose waters fail not.
One of the great marvels of the Roman Empire was the invention of the aqueduct system to provide water over vast distances. It was an absolutely ingenious method which made use of gravity, with stone arches to support the water channels. An aqueduct was built in 109 AD which carried water to the city of Segovia for eighteen hundred years. For nearly sixty generations this aqueduct provided cool water from the mountains above. But fairly recently, it was beginning to collapse.
A well-intentioned citizen, observing the ancient structure, remarked, “This aqueduct is so great a marvel that it ought to be preserved for our children, as a museum piece. We shall relieve it of its centuries-long labor.” So the city decided to construct a modern water system with iron pipes to carry the water, intending to give the aqueduct a long-deserved rest. What they failed to realize, of course, was that attempting to preserve the aqueduct by stopping the flow of water through it, assured its rapid disintegration! As the sun beat down on the now dry mortar and stone, the centuries old structure quickly began to fall apart. Amazingly, nearly two millenia of service would not accomplish the destructive work of less than a century of idleness!
This story ought to really encourage us in Kingdom work…since, continuing to allow Yeshua’s living water to flow through us, we are constantly renewed and preserved, rather than drying up with idleness and atrophy. So…with so much work to be done, let us do it with the life-giving stream: the ever-renewing vitality of Yeshua’s living water!

[worthy_plugins_devotion_single_body]Elul is unlike any other month. As we mentioned yesterday, it is the 12th month on the civil calendar and the 6th on the prophetic calendar. This dual position gives Elul a unique character — it both closes a cycle and prepares for a new one. That is why the shofar sounds each day during Elul: it is a wake-up call, reminding us to reflect, repent, and return to the Lord before the great and awesome days of the Fall Feasts.
This begins a very special season on God’s calendar — the month of preparation before the Fall Feasts. The month of Elul is unique: it is the 12th month on the civil calendar and the 6th month on the prophetic/biblical calendar. Each day of Elul is marked by the blowing of the shofar, a trumpet call that awakens the soul. These daily blasts prepare our hearts for Yom Teruah (the Feast of Trumpets, Rosh Hashanah) and ultimately for Yom Kippur (the Day of Atonement).
We have come to the final meditation in this journey through the Z’roah, the Arm of the LORD. From the Arm that redeemed Israel out of Egypt, to the Arm that pierced the dragon, to the Arm that is coming with reward — all of these revelations lead us here: the Arm that brings His people into rest.
Isaiah’s vision looks ahead — not only to the Arm of the LORD revealed in the Exodus or even in the cross, but to the day when that same Arm will come again in glory. This is not a picture of brute force but of purposeful arrival. The Z’roah — the Arm of the LORD — comes clothed with strength to establish His rule, and He does not come empty-handed. His reward is with Him, and His work is before Him. The promise is sure: He is coming, and He is rewarding.
Isaiah recalls the Exodus as the supreme display of God’s Z’roah, His Arm of glory. Though the people saw Moses raise his staff over the Red Sea, it was not Moses’ power that split the waters. Behind the prophet’s hand was the Arm of the LORD — majestic, glorious, and unstoppable. The sea parted not to honor Moses, but to exalt the Name of the God who sent him. The Red Sea became a stage for God to reveal His glory, so that His Name would echo through generations as the Deliverer of His people.
Jeremiah uttered these words when everything around him looked hopeless. Babylon’s armies surrounded Jerusalem, the city was on the brink of destruction, and yet God told Jeremiah to buy a field as a prophetic sign that restoration would come. The prophet responded in awe: the God who created the heavens and the earth by His outstretched arm (bizroa netuyah) is not bound by human circumstances. The same God who set galaxies in place and boundaries for the seas is the God who still moves to redeem His people. Truly, nothing is too hard for Him.
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.
