Acts 4:13 Now when they saw the boldness of Peter and John, and perceived that they were unlearned and ignorant men, they marvelled; and they took knowledge of them, that they had been with Jesus.
Just a few weeks prior to this incident, the disciples were trembling for their lives as their Lord was arrested and then crucified. They had all fled in the Garden of Gethsemane and then Peter, whose boldness was legendary, had denied him three times. The fact that they had been serving with Yeshua (Jesus) for three years, witnessing many miracles, including Peter’s amazing walk on the water, apparently did not inspire the necessary courage to watch for an hour or to stick with Him to the end. Perhaps the miraculous had become a bit commonplace for them, so that when the threat to Yeshua came full force, they floundered and failed miserably.
What happened that changed their state of being so dramatically in this encounter with the Jewish leaders? I believe it was two things: one, that they had seen their Lord resurrected from the dead, and two, that they were now filled with that resurrection life and power themselves, by the Holy Spirit. The power of the resurrection was within and upon them! The reality and security of God’s indwelling Presence and power, and His words “Be not afraid of them that kill the body, and after that have no more that they can do”, inspired a boldness far beyond any merely human courage.
This boldness amazed the Sadducees and Pharisees who despised Peter and John as “unlearned and ignorant”men. They marveled at the unabashed fearlessness of the apostles whose knowledge was of a different and superior kind: the knowledge of their RISEN and RESURRECTED Lord. And then they noted, that these men had been with Yeshua (Jesus)!
This power is yours, and it is mine, if we continue to be filled with the Holy Spirit, not quenching or grieving Him. We, too, will confound and amaze the “authorities” of our day with the holy boldness of resurrection life, and though they may despise our humble circumstances, they also will take note that, “we have been with Jesus”.

[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.
