I am the LORD your God, who stirs up the sea so that its waves roar— the LORD of hosts is his name.
English Standard Version (ESV)
This passage begins with God comforting his people, reminding them of their origins and His power to restore them.

This powerful reminder serves as the foundation for His promises of future restoration and security.
Have you ever felt overwhelmed by circumstances, like waves crashing down on you? God uses the imagery of a raging sea to remind us of His power.
The verse highlights God's absolute control over the chaotic forces of nature, specifically the sea. When it says God 'stirs up the sea so that its waves roar,' it's not just a poetic description. It points to a God who can unleash terrifying power but also, as other passages suggest, can command storms to cease and bring about calm.
Divine Command
This isn't about a God who is surprised by chaos, but one who orchestrates it. The ancient understanding of the sea often associated it with untamable, monstrous forces. By claiming power over the sea, God declares His supremacy over all such threats and the forces that threaten to overwhelm His people.
Why does God bring up a dramatic, ancient event like dividing the Red Sea? It's a foundational reminder of His faithfulness and strength.
The phrase 'who divided the sea' is a direct reference to the Exodus from Egypt, specifically the miraculous parting of the Red Sea (Exodus 14). This event was not just a historical moment; it was God's definitive act of delivering His people from slavery and establishing His covenant with them.
A Guarantee of Future Deliverance
By reminding the people of this monumental act, God is saying: 'Remember what I did for your ancestors. That same power and faithfulness are still at work for you now.' It serves as a powerful assurance that the God who defeated the mighty Egyptian army and led His people through a dry path in the sea is more than capable of overcoming their current difficulties and enemies.
Ask a follow-up
What does it mean that God's name is 'the LORD of hosts'? It speaks to His ultimate authority over everything.
The title 'LORD of hosts' (Hebrew: Yahweh Tsebaoth) is one of the most significant and frequently used titles for God in the Old Testament. It literally means 'LORD of Armies' or 'LORD of Heavenly Armies'.
Commander of All Forces
This name signifies God's supreme authority and power not only over the armies of Israel but also over all the armies of heaven and earth – including the natural elements like the roaring seas. It assures His people that the God who commands the waves is also the ultimate commander of all powers, seen and unseen. When Israel faced overwhelming opposition, remembering God as the 'LORD of Hosts' was a reminder that their God possessed greater power than any enemy force they could face.
