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]Elul is unlike any other month. As we mentioned yesterday, it is the 12th month on the civil calendar and the 6th on the prophetic calendar. This dual position gives Elul a unique character — it both closes a cycle and prepares for a new one. That is why the shofar sounds each day during Elul: it is a wake-up call, reminding us to reflect, repent, and return to the Lord before the great and awesome days of the Fall Feasts.
This begins a very special season on God’s calendar — the month of preparation before the Fall Feasts. The month of Elul is unique: it is the 12th month on the civil calendar and the 6th month on the prophetic/biblical calendar. Each day of Elul is marked by the blowing of the shofar, a trumpet call that awakens the soul. These daily blasts prepare our hearts for Yom Teruah (the Feast of Trumpets, Rosh Hashanah) and ultimately for Yom Kippur (the Day of Atonement).
We have come to the final meditation in this journey through the Z’roah, the Arm of the LORD. From the Arm that redeemed Israel out of Egypt, to the Arm that pierced the dragon, to the Arm that is coming with reward — all of these revelations lead us here: the Arm that brings His people into rest.
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.
