1 Chronicles 12:33 Of Zebulun, there were 50,000 who went out in the army, who could draw up in battle formation with all kinds of weapons of war and helped David with an undivided heart.
Colossians 3:23-25 Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving.
50,000 soldiers from the tribe of Zebulun served in David’s army with UNDIVIDED (some translations: “not double-hearted”) hearts. Can you imagine a skilled army with this level of loyalty and devotion?
An undivided heart is one of the most powerful things on earth. Singleness of purpose will flow from the life of a person whose heart is undivided. Couples whose hearts are devoted to the Lord this way will preserve their marriages, no matter how difficult their issues and problems become. Intercessors whose hearts are filled with a single purpose will ultimately demolish terrible strongholds. Missionaries with vision and absolute loyalty, will be able to take entire nations for Christ. One woman will pour out ointment worth a year’s salary on her savior’s head. An undivided heart is one of the most powerful things on earth.
Yeshua (Jesus) inspires and empowers undivided hearts. If you really know him well, you will be very much like the men of Zebulun were in their loyalty toward David.
Check your heart. Is it inspired by the beauty, heroism, and love of the Messiah? If not, you just don’t know him well enough.

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.
