Isaiah 29:13-14 Therefore the Lord said: “Inasmuch as these people draw near with their mouths And honor Me with their lips, But have removed their hearts far from Me, And their fear toward Me is taught by the commandment of men, Therefore, behold, I will again do a marvelous work among this people, A marvelous work and a wonder; For the wisdom of their wise men shall perish, And the understanding of their prudent men shall be hidden.”
An ancient story is told of a King of Spain who was to visit a poor country village. Upon hearing of his plan to visit them, the people seemed excited to offer a great celebration that would show their adoration and love for their king. But the villagers didn’t have much to offer.
In the midst of their quandary someone proposed that, since so many villagers made their own wines, they might each choose his best wine, and combine them in a barrel to present to the king as a gift from the village. So they did, each wine-maker bringing a flagon with which to fill the barrel. Then, they anxiously awaited the arrival of their sovereign.
When the King arrived, he was ceremoniously presented with a silver cup and invited to draw wine from the barrel. As he filled his silver chalice, he was surprised when he tasted only water. Where was the wine? Each villager had reasoned, “I’ll withhold my best wine and give water. There will be so many cups of excellent wine poured into the barrel that mine will never be missed.”
Here was a town full of people whose private greed completely overcame their public enthusiasm. The indictment of Isaiah the prophet suited them perfectly: “these people draw near with their mouths and honor Me with their lips, but have removed their hearts far from Me..”
Yet our God looks at the heart, and He knows well when we are going through the motions of showing love and admiration for him, without any truth or sincerity.
Hypocrisy is a serious offense to our God. He would rather we honestly withhold then pretend to be generous. How often do we act publicly to be seen by men in a certain light, while in fact, our motive is self-seeking? So God will have to do another marvellous work to expose our hypocrisy, because of His love for us, for He knows when our “wine” is really “water”. But wouldn’t we rather offer our very best wine right from the start?

[worthy_plugins_devotion_single_body]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.
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.
