Isaiah 59:16-19 He saw that there was no man, And wondered that there was no intercessor; Therefore His own arm [z’roah in Hebrew] brought salvation for Him; And His own righteousness, it sustained Him. For He put on righteousness as a breastplate, And a helmet of salvation on His head; He put on the garments of vengeance for clothing, And was clad with zeal as a cloak. According to their deeds, accordingly He will repay, Fury to His adversaries, Recompense to His enemies; The coastlands He will fully repay. So shall they fear The name of the Lord from the west, And His glory from the rising of the sun; When the enemy comes in, like a flood The Spirit of the Lord will lift up a standard against him.
The Hebrew expression in this verse from Isaiah is rich with meaning. The root “nus” (from the expression “raise up a standard”) is related to or sounds like numerous words which mean “sign”, “miracle”, “to drive away”, “to flee”, “cause to disappear”, “a waving flag”. This abundance of meanings in Isaiah’s poetic style reveals the multiple dimensions of God’s revelation; in this case, the way he deals with evil. The assertion in this word is that the Spirit of YHVH will be powerfully activated when evil comes.
Whether the enemy comes in like a flood, and then the LORD raises a standard against him…or, the enemy comes in, and like a flood, the LORD works miraculously and drives him away, the clear meaning and promise is that the presence of evil will not go unnoticed. God will respond powerfully, in His own way, and in His own time.
We’ve often spoken of the increase of wickedness in these last days; virtually every day some new scandal appears. Evil is on the rise; its power being consolidated in many areas of social, political, and personal life. Our identification with the one true God who raises His standard in response to this wickedness, calls us to be His “standard bearers” in the midst of the flood of evil around us. This is not easy, but is a high calling for faith-filled and disciplined saints.
Our challenge now, more than ever before, is, do not be overcome by evil, but overcome evil with good. We cannot bear Yeshua’s standard if we yield to become like the world around us. Only by abiding, praying, staying close to Him, can we represent our Lord. Let’s continue to encourage one another…daily.

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.
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.
