Isaiah 22:22 And the key of the house of David will I lay upon his shoulder; so he shall open, and none shall shut; and he shall shut, and none shall open.
Isaiah 9:6-7 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this.
Revelation 3:7-9 And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth; I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name.
The book of Isaiah, often called the Old Testament Gospel, reveals that a child was to be born and his name called “The Mighty God, and the Everlasting Father”. We know that this Child was Yeshua (Jesus) of Nazareth, that He is the unique Son of God, the express image of the invisible God. The throne of David was to be given to Him and He now holds its “key”, a symbol of the right and authority of His reign, which will be consummated when He returns to this world and restores the Kingdom to Israel [Acts 1:6-7].
The glorified Yeshua, speaking to the church at Philadelphia, mentions this “key of David”, reminding them of His authority, and expressing His approval of their deeds, patience and faithfulness to His word, and His love for them. The Lord’s approval comes with a mandate. Knowing that they have but a little strength, notwithstanding, He sets before them an open door that no man can shut. They are to move out, through this “door”, having been approved, and now equipped to represent Him.
“Philadelphia” means “brotherly love”. Can it be coincidence that this church is encouraged with a reminder that the beloved psalmist/King David’s key and authority are now held by Yeshua, who sends them on a mission of love?
Those of us whose patience has been tested, will also receive His approval, His protection, and His mandate, just as the church of Philadelphia did. Since God is love, and love is patient, our preparation of patience will equip us with His power to fulfill His mandate, and to go through His “open door”. So doing, we will hasten the coming of His glorious Kingdom. Even so, come Lord Yeshua (Jesus)!

[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.
