Exodus 12:16-17 On the first day there shall be a holy convocation, and on the seventh day there shall be a holy convocation for you. No manner of work shall be done on them; but that which everyone must eat--that only may be prepared by you. So you shall observe the Feast of Unleavened Bread, for on this same day I will have brought your armies out of the land of Egypt. Therefore you shall observe this day throughout your generations as an everlasting ordinance.
Exodus 14:11-31 Then they said to Moses, "Because there were no graves in Egypt, have you taken us away to die in the wilderness? Why have you so dealt with us, to bring us up out of Egypt? Is this not the word that we told you in Egypt, saying, 'Let us alone that we may serve the Egyptians'? For it would have been better for us to serve the Egyptians than that we should die in the wilderness." And Moses said to the people, "Do not be afraid. Stand still, and see the salvation of the LORD, which He will accomplish for you today. For the Egyptians whom you see today, you shall see again no more forever. The LORD will fight for you, and you shall hold your peace.' And the LORD said to Moses, "Why do you cry to Me? Tell the children of Israel to go forward. But lift up your rod, and stretch out your hand over the sea and divide it. And the children of Israel shall go on dry ground through the midst of the sea. And I indeed will harden the hearts of the Egyptians, and they shall follow them. So I will gain honor over Pharaoh and over all his army, his chariots, and his horsemen. Then the Egyptians shall know that I am the LORD, when I have gained honor for Myself over Pharaoh, his chariots, and his horsemen." And the Angel of God, who went before the camp of Israel, moved and went behind them; and the pillar of cloud went from before them and stood behind them. So it came between the camp of the Egyptians and the camp of Israel. Thus it was a cloud and darkness to the one, and it gave light by night to the other, so that the one did not come near the other all that night. Then Moses stretched out his hand over the sea; and the LORD caused the sea to go back by a strong east wind all that night, and made the sea into dry land, and the waters were divided. So the children of Israel went into the midst of the sea on the dry ground, and the waters were a wall to them on their right hand and on their left. And the Egyptians pursued and went after them into the midst of the sea, all Pharaoh's horses, his chariots, and his horsemen. Now it came to pass, in the morning watch, that the LORD looked down upon the army of the Egyptians through the pillar of fire and cloud, and He troubled the army of the Egyptians. And He took off their chariot wheels, so that they drove them with difficulty; and the Egyptians said, "Let us flee from the face of Israel, for the LORD fights for them against the Egyptians." Then the LORD said to Moses, "Stretch out your hand over the sea, that the waters may come back upon the Egyptians, on their chariots, and on their horsemen." And Moses stretched out his hand over the sea; and when the morning appeared, the sea returned to its full depth, while the Egyptians were fleeing into it. So the LORD overthrew the Egyptians in the midst of the sea. Then the waters returned and covered the chariots, the horsemen, and all the army of Pharaoh that came into the sea after them. Not so much as one of them remained. But the children of Israel had walked on dry land in the midst of the sea, and the waters were a wall to them on their right hand and on their left. So the LORD saved Israel that day out of the hand of the Egyptians, and Israel saw the Egyptians dead on the seashore. Thus Israel saw the great work which the LORD had done in Egypt; so the people feared the LORD, and believed the LORD and His servant Moses.
Exodus 14:5-9 Now it was told the king of Egypt that the people had fled, and the heart of Pharaoh and his servants was turned against the people; and they said, "Why have we done this, that we have let Israel go from serving us?" So he made ready his chariot and took his people with him. Also, he took six hundred choice chariots, and all the chariots of Egypt with captains over every one of them. And the LORD hardened the heart of Pharaoh king of Egypt, and he pursued the children of Israel; and the children of Israel went out with boldness. So the Egyptians pursued them, all the horses and chariots of Pharaoh, his horsemen and his army, and overtook them camping by the sea beside Pi Hahiroth, before Baal Zemphon.
