Then Pharaoh called Moses and said, "Go, worship Jehovah; only let your flocks and your herds stay behind; let your little ones go with you." But Moses said, "You must also give us animals for sacrifices and burnt-offerings, that we may offer a sacrifice to Jehovah our God. Our cattle too must go with us; not a hoof shall be left behind, for we must take these to offer to Jehovah our God, and we do not know what we must offer to Jehovah until we arrive there." But Jehovah let Pharaoh's heart remain stubborn, and he would not let them go. And Pharaoh said to him, "Go away from me; take care that you never come to me again; for on the day that you come to me you shall die." Moses replied, "You have spoken truly, I shall never see you again." Moses said to Pharaoh, "Jehovah declares: 'About midnight I will go through all of Egypt. All the eldest sons in the land of Egypt shall die, from the eldest son of Pharaoh who sits upon his throne, even to the eldest son of the slave girl who is behind the mill, and all the first-born of the cattle. There shall be a great cry of sorrow all over the land of Egypt, such as has never been before and never shall be again.' But not a single dog shall bark at any of the Israelites nor their animals, that you may know that Jehovah does make a difference between the Egyptians and Israelites. All these your servants shall come to me and bow down before me, saying, 'Go away, together with all the people that follow you.' After that I will go away." And Moses went from Pharaoh in great anger. THE ESCAPE FROM EGYPT Moses called together all the leaders of Israel, and said to them, "Take lambs from the herds according to your families and kill the passover lamb. You shall also take a bunch of hyssop and dip it in the blood that is in the basin and strike the lintel and the two door posts with the blood that is in the basin. And not one of you shall go out of the door of his house until morning, for Jehovah will pass through to kill the Egyptians, and when he sees the blood upon the lintel and on the two door posts, he will pass over the door and will not let the destroyer come into your houses to destroy you. You and your children shall observe this event as a custom forever. "When your children shall say to you, 'What do you mean by this service?' you shall say, 'It is the sacrifice of the passover of Jehovah, for he passed over the houses of the Israelites in Egypt, when he destroyed the Egyptians and released our people.'" Then the people bowed their heads and worshipped; and the Israelites went and did as Jehovah had commanded Moses and Aaron.
