Exodus 14:5-14

When the king of Egypt was told that the people had fled, Pharaoh and his servants had a change of heart toward the people, and they said, “What is this that we have done? We have let Israel go from serving us!” So Pharaoh harnessed horses to his war-chariots [for battle] and took his army with him; and he took six hundred chosen war-chariots, and all the other war-chariots of Egypt with fighting charioteers over all of them. The LORD hardened the heart of Pharaoh, king of Egypt, and he pursued the Israelites, as they were leaving confidently and defiantly. [Acts 13:17] The Egyptians chased them with all the horses and war-chariots of Pharaoh, his horsemen and his army, and they overtook them as they camped by the sea, beside Pi-hahiroth, in front of Baal-zephon. As Pharaoh approached, the Israelites looked up and saw the Egyptians marching after them, and they were very frightened; so the Israelites cried out to the LORD. Then they said to Moses, “Is it because there are no graves in Egypt that you have taken us away to die in the wilderness? What is this that you have done to us by bringing us out of Egypt? Did we not say to you in Egypt, ‘Leave us alone; let us serve the Egyptians?’ For it would have been better for us to serve the Egyptians [as slaves] than to die in the wilderness.” Then Moses said to the people, “Do not be afraid! Take your stand [be firm and confident and undismayed] and see the salvation of the LORD which He will accomplish for you today; for those Egyptians whom you have seen today, you will never see again. The LORD will fight for you while you [only need to] keep silent and remain calm.”
