“Yahweh said to Moses and Aaron: ‘I shall go through the land of Egypt on this night, and I shall strike every firstborn in the land of Egypt, from man to beast; and against all the gods of Egypt I shall mete out punishment – I am the Jealous One. The blood shall be a sign for you upon the houses where you are; when I shall see the blood and I shall pass over you; there shall not be a plague of destruction upon you when I strike in the land of Egypt.'”
“Moses called to all the elders of Israel and said to them: ‘Draw forth or buy for yourselves one of the flock for your families, and slaughter the pesach-offering. You shall take a bundle of hyssop and dip it into the blood that is in the basin, and as for you, no man shall leave the entrance of his house until morning. Yahweh will pass through to smite Egypt, and He will see the blood that is on the lintel and the two doorposts; and Yahweh will pass over the entrance and He will not permit the destroyer to enter your homes to smite.’ The Children of Israel went and did as Yahweh commanded Moses and Aaron, so did they do.”
“It was at midnight that Yahweh smote every firstborn in the land of Egypt, from the firstborn of Pharaoh sitting on his throne to the firstborn of the captive who was in the dungeon; and every firstborn animal. Pharaoh rose up at midnight, he and all his servants and all Egypt, and there was a great outcry in Egypt, for there was not a house where there was no corpse. He called to Moses and Aaron at night and said: ‘Rise up, go out from among my people, even you, even the Children of Israel; go and serve Yahweh as you have spoken! Take even your sheep and even your cattle, as you have spoken, and go – and bless me, as well!’ Egypt imposed itself strongly upon the people to hasten to send them out of the land, for they said: ‘ We are all dying!’ The Children of Israel carried out the word of Moses; they requested from the Egyptians silver vessels, gold vessels, and garments. Yahweh gave the people favor in the eyes of the Egyptians and they granted their request – so they emptied Egypt” (Ex 12:1, 12-13, 21-23, 29-33, 35-36).
