Came across this verse in the story of Israel crossing the Red Sea.
"The Lord will fight for you, and you have only to be silent."
Preceding it, Moses says to Israel in verse 13, "Fear not, stand firm, and see the salvation of the Lord, which he will work for you today..."
Proceeding it, the Lord says to Moses in verse 17b-18, "And I will get glory over Pharaoh and all his host, his chariots, and his horsemen. And the Egyptians shall know that I am the Lord, when I have gotten glory over Pharaoh, his chariots, and his horsemen."
We know the plot.
The chapter ends in verse 31, "Israel saw the great power that the Lord used against the Egyptians, so the people feared the Lord, and they believed in the Lord..."
What jumps off the page is the Lord's perfect nature to make a promise, and get it done. No questions, no plan B's. He chooses to rescue Israel. He declares his will to do so. And accomplishes the task.
Also, what we see in this story like so many others in scripture, is the Lord's characteristic purpose in PROCLAIMING HIS NAME and REDEEMING HIS PEOPLE.
What a mighty God we serve. What an incredible confidence we have in His power not only to act for us, but then bring us to Himself.
