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]Psalm 98 is a victory psalm — a call to lift up a “new song” because the Z’roah, the holy arm of the LORD, has brought decisive triumph. In Hebrew thought, the arm is the active extension of the will, the power that brings intention into reality. To call it “holy” is to declare that it is set apart, dedicated fully to God’s purpose, incapable of corruption. The psalmist celebrates that salvation is not a hidden act, but an open demonstration — God’s righteousness revealed before the eyes of the nations.
This is one of the most intimate revelations of the Z’roah in Scripture. God looks for a human intercessor but finds none. No man can bridge the gap. So His own Arm accomplishes the work. In Hebrew, v’tosha lo zeroa — “His arm saved for Him” — reveals that salvation originates from within God Himself, not from any outside help. Isaiah adds that His own righteousness sustained Him — it upheld His resolve to save — and His fury upheld Him, a holy passion that would not rest until justice was accomplished.
To “bare” the arm means to roll up the sleeve and reveal the full readiness for action. In Isaiah’s prophecy, this is a global unveiling — no longer hidden, the Z’roah is on display for all nations to witness. This speaks directly of Yeshua’s (Jesus’) public ministry and, ultimately, His crucifixion.
The Hebrew phrase “z’roah moshel lo” paints the picture of an arm that governs with both strength and care. The same Z’roah that brought Israel out of Egypt in power now establishes righteous order and sustains His people in love. Deliverance without rulership is incomplete; the Redeemer becomes the King — and the King rules as a Shepherd. The Arm does not act independently but moves in perfect submission to the Head, carrying out the will of the Father.
I’ll be doing a series on the “Arm of God,” beginning with this first message — The Arm that Redeems. The Hebrew Z’roah (זְרוֹעַ) means “arm” or “strength,” and in ancient Hebrew culture, the arm symbolizes active power in motion — strength applied for a purpose. In the Exodus account, God tells Moses He will redeem Israel “with an outstretched arm” (bizroa netuyah). This was not poetic metaphor; it was God’s declaration of decisive intervention. The Z’roah is the covenant-keeping arm that moves history, enforces promises, and breaks oppression. Every Pesach (Passover), during the seder — the festive meal of remembrance — the roasted lamb shank bone, the Z’roah, rests on the plate as a silent yet powerful witness to God’s mighty deliverance.
These closing verses of Psalm 118 begin with an unshakable proclamation: “The LORD is God.” In Hebrew, it’s emphatic — YHVH, He is El — the declaration that all authority, holiness, and sovereignty belong to Him alone. Yet this is not just a statement of who He is — it’s a testimony of what He has done: “He has made His light to shine upon us.” This light is more than the glow of the sun — it is the revelation of His presence, the warmth of His favor, and the piercing truth that chases away every shadow. His light doesn’t simply illuminate — it transforms.
Psalm 118:24 is not merely about enjoying a new day — it is a prophetic declaration of a divinely appointed moment. “This is the day the LORD has made” speaks of a kairos moment in history when heaven and earth converge. It points to the day when Messiah would be revealed, salvation would walk into Jerusalem, and God’s covenant plan would take a dramatic step forward. This is not the casual celebration of a sunrise — it is the joyful response to God’s redemptive unfolding.
