Third reading: Exodus 14:15--15:1

The Lord said to Moses, ‘Why do you cry to me so? Tell the sons of Israel to march on. For yourself, raise your staff and stretch out your hand over the sea and part it for the sons of Israel to walk through the sea on dry ground. I for my part will make the heart of the Egyptians so stubborn that they will follow them. So shall I win myself glory at the expense of Pharaoh, of all his army, his chariots, his horsemen. And when I have won glory for myself, at the expense of Pharaoh and his chariots and his army, the Egyptians will learn that I am the Lord.’

Then the angel of God, who marched at the front of the army of Israel, changed station and moved to their rear. The pillar of cloud changed station from the front to the rear of them, and remained there. It came between the camp of the Egyptians and the camp of Israel. The cloud was dark, and the night passed without the armies drawing any closer the whole night long.

Moses stretched out his hand over the sea. The Lord drove back the sea with a strong easterly wind all night, and he made dry land of the sea. The waters parted and the sons of Israel went on dry ground right into the sea, walls of water to right and to left of them. The Egyptians gave chase: after them they went, right into the sea, all Pharaoh’s horses, his chariots, and his horsemen.

In the morning watch, the Lord looked down on the army of the Egyptians from the pillar of fire and of cloud, and threw the army into confusion. He so clogged their chariot wheels that they could scarcely make headway. ‘Let us flee from the Israelites,’ the Egyptians cried. ‘The Lord is fighting for them against the Egyptians!’

‘Stretch out your hand over the sea,’ the Lord said to Moses, ‘that the waters may flow back on the Egyptians and their chariots and their horsemen.’

Moses stretched out his hand over the sea and, as day broke, the sea returned to its bed. The fleeing Egyptians marched right into it, and the Lord overthrew the Egyptians in the very middle of the sea. The returning waters overwhelmed the chariots and the horsemen of Pharaoh’s whole army, which had followed the Israelites into the sea; not a single one of them was left. But the sons of Israel had marched through the sea on dry ground, walls of water to right and to left of them.

That day, the Lord rescued Israel from the Egyptians, and Israel saw the Egyptians lying dead on the shore. Israel witnessed the great act that the Lord had performed against the Egyptians, and the people venerated the Lord; they put their faith in the Lord and in Moses, his servant.

It was then that Moses and the sons of Israel sang this song in honour of the Lord:
