Exodus 12:28-38

28 They did just as the Lord commanded Moses and Aaron.
29 At midnight the Lord killed all the firstborn sons in the land of Egypt -- from the firstborn of the king who sat on the throne to the firstborn of the prisoner in jail. Also, all the firstborn farm animals died.
30 The king, his officers, and all the Egyptians got up during the night because someone had died in every house. So there was a loud outcry everywhere in Egypt.
31 During the night the king called for Moses and Aaron and said, "Get up and leave my people. You and your people may do as you have asked; go and worship the Lord.
32 Take all of your flocks and herds as you have asked, and go. And also bless me."
33 The Egyptians also asked the Israelites to hurry and leave, saying, "If you don't leave, we will all die!"
34 So the people took their dough before the yeast was added. They wrapped the bowls for making dough in clothing and carried them on their shoulders.
35 The Israelites did what Moses told them to do and asked their Egyptian neighbors for things made of silver and gold and for clothing.
36 The Lord caused the Egyptians to think well of them, and the Egyptians gave the people everything they asked for. So the Israelites took rich gifts from them.
37 The Israelites traveled from Rameses to Succoth. There were about six hundred thousand men walking, not including the women and children.
38 Many other people who were not Israelites went with them, as well as a large number of sheep, goats, and cattle.
