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 sang this song in honour of the Lord:

I will sing to the Lord, glorious his triumph!

At the breath of your anger the waters piled high;
  the moving waters stood up like a dam.
The deeps turned solid in the midst of the sea.
  The enemy said: ‘I will pursue and overtake them,
I will divide my plunder, I shall have my will.
  I will draw my sword, my hand shall destroy them.’

I will sing to the Lord, glorious his triumph!

You blew with your breath, the sea closed over them.
  They went down like lead into the mighty waters.
  You stretched forth your hand, the earth engulfed them.

I will sing to the Lord, glorious his triumph!

You will lead your people and plant them on your mountain,
  the place, O Lord, where you have made your home,
  the sanctuary, Lord, which your hands have made.

I will sing to the Lord, glorious his triumph!

Alleluia, alleluia!
Whenever anyone obeys what Christ has said,
God’s love comes to perfection in him.
Alleluia!
