Exodus 15:1-6 and Exodus 14:5-18

Exodus 15:1-6
1 Then Moses and the sons of Israel sang this song to the Lord, and they said: "Let us sing to the Lord, for he has been gloriously magnified: the horse and the rider he has cast into the sea.
2 The Lord is my strength and my praise, and he has become my salvation. He is my God, and I shall glorify him. He is the God of my father, and I shall exalt him.
3 The Lord is like a fighting man. Almighty is his name.
4 The chariots of Pharaoh, and his army, he has cast into the sea; his elect leaders have been submerged in the Red Sea.
5 The abyss has covered them. They descended into the depths like a stone.
6 Your right hand, O Lord, has been magnified in strength. Your right hand, O Lord, has struck down the enemy.
Exodus 14:5-18
5 And it was reported to the king of the Egyptians that the people had fled. And the heart of Pharaoh and of his servants was changed about the people, and they said, "What did we intend to do, so that we released Israel from serving us?"
6 Therefore, he harnessed his chariot, and he took all his people with him.
7 And he took six hundred chosen chariots, and whatever chariots were in Egypt, and also the leaders of the whole army.
8 And the Lord hardened the heart of Pharaoh, king of Egypt, and he pursued the sons of Israel. But they were taken away by an exalted hand.
9 And when the Egyptians followed the footsteps of those who preceded them, they found them in a camp above the sea. All the horses and chariots of Pharaoh, and the entire army, were in Pihahiroth, opposite Baal-zephon.
10 And when Pharaoh had drawn near, the sons of Israel, lifting up their eyes, saw the Egyptians behind them. And they were very afraid. And they cried out to the Lord.
11 And they said to Moses: "Perhaps there were no graves in Egypt, for which reason you took us to die in the wilderness. What is it that you intended to do, in leading us out of Egypt?
12 Is this not the word that we spoke to you in Egypt, saying: Withdraw from us, so that we may serve the Egyptians? For it was much better to serve them, than to die in the wilderness."
13 And Moses said to the people: "Do not be afraid. Stand firm and see the great wonders of the Lord, which he will do today. For the Egyptians, whom you now see, will never again be seen, forever.
14 The Lord will fight on your behalf, and you will remain silent."
15 And the Lord said to Moses: "Why cry out to me? Tell the sons of Israel to continue on.
16 Now, lift up your staff, and extend your hand over the sea and divide it, so that the sons of Israel may walk through the midst of the sea on dry ground.
17 Then I will harden the heart of the Egyptians, so as to pursue you. And I will be glorified in Pharaoh, and in all his army, and in his chariots, and in his horsemen.
18 And the Egyptians will know that I am the Lord, when I will be glorified in Pharaoh, and in his chariots, as well as in his horsemen."
