Exodus 15:23-26 And when they came to Marah, they could not drink of the waters of Marah, for they were bitter: therefore the name of it was called Marah. And the people murmured against Moses, saying, What shall we drink? And he cried unto the LORD; and the LORD shewed him a tree, which when he had cast into the waters, the waters were made sweet: there he made for them a statute and an ordinance, and there he proved them, And said, If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth thee.
Murmuring or complaining is one of those sins that are overlooked. Sometimes we get so focused on the “big sins” such as murder and adultery that we overlook this sin — but the Lord doesn’t give this sin a free pass — quite the opposite. It’s a hidden killer! This sin unleashed a plague that killed thousands of Israelites! [Numbers 16]
In this passage, we read how the Israelites, who were desperately thirsty, looked only at the fact that the water they had come to was bitter and undrinkable. How quickly they forgot their God, who had led them out of Egypt with signs and wonders. They had just witnessed His dividing of the Red Sea and the destruction of those who had enslaved them. And yet, so quickly, they returned to looking only with their natural eyes at the problem in front of them, completely forgetting the miracle-working power of their God! And so they murmured against Moses. But honestly, weren’t they really murmuring against God? Once again, Moses interceded for them, revealing the faithfulness of His God to answer every impossible dilemma and provide for every need; and again, setting them the example: they simply needed to go to the Lord!
So often, just like the Israelites, we focus on our desperate situation with our physical eyes and not with eyes of faith and then fall into the trap of complaining. And if you’re like me, once I start, it can be really hard to stop…until the Lord stops me, right in my tracks, and He reminds me –- aren’t you really complaining against me? I have to remember to see that I actually hinder the Lord’s answers to my problems by unbelief…which leads to the sin of murmuring!
Let’s not allow this sin to gain a foothold — because it can easily become a stronghold! The same wonder-working God that led the children of Israel out of Egypt is still at work today — but are we hindering Him? If we are grumbling and complaining, the answer is, “YES”! And in so doing, until we stop, we are missing out on His answers and blessings, which are waiting in the wings to meet our faith in Him!

[worthy_plugins_devotion_single_body]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.
