EXODUS 14:13-14 - And Moses said unto the people, Fear ye not, stand still, and see the salvation of the LORD, which he will shew to you to day: for the Egyptians whom ye have seen to day, ye shall see them again no more for ever. The LORD shall fight for you, and ye shall hold your peace.
As Moses leads the Children of Israel out of Egypt, Pharoah regrets his decision to let them leave and sends his army after them. It included 600 choice chariots and all the chariots of Egypt. Rightfully so, the people are frightened. They could see Pharaoh's armies on one side and the Red Sea on the other. They seemed to have no chance for escape. God led Israel into what seemed to be a trap. There was no way of escape except the way they had come in, and the Egyptian army had that path blocked. The children of Israel cried out to the LORD: Israel did the right thing. When we find ourselves in dangerous places with no easy escape, we must cry out to God, because God is our refuge and strength, a very present help in trouble (Psalm 46:1).
Moses responds with great courage. Do not be afraid: At this point, Moses had no idea how God would help them in the situation. All he knew was God certainly would help. In a sense, Moses knew he was in such a bad situation that God had to come through. When we see that our only help is God, we are more likely to trust Him. Sometimes it is the little things - the things we think we can do in our own strength - that get us down, not the big things that we know only God can do.
Stand still: Moses told the people of Israel to stop. This is often the LORD's direction to the believer in a time of crisis. Despair will cast you down, keeping you from standing. Fear will tell you to retreat. Impatience will tell you to do something now. Presumption will tell you to jump into the Red Sea before it is parted. Yet as God told Israel He often tells us to simply stand still and hold your peace as He reveals His plan. See the salvation of the LORD: Moses didn't know what God would do. Yet he knew what the result would be. He knew that God would save His people and that the enemies of the LORD would be destroyed. He could say to Israel, "the LORD will fight for you."
