Exodus 12:29-38

And that night at midnight, the LORD struck down all the firstborn sons in the land of Egypt, from the firstborn son of Pharaoh, who sat on his throne, to the firstborn son of the prisoner in the dungeon. Even the firstborn of their livestock were killed. Pharaoh and all his officials and all the people of Egypt woke up during the night, and loud wailing was heard throughout the land of Egypt. There was not a single house where someone had not died. Pharaoh sent for Moses and Aaron during the night. “Get out!” he ordered. “Leave my people—and take the rest of the Israelites with you! Go and worship the LORD as you have requested. Take your flocks and herds, as you said, and be gone. Go, but bless me as you leave.” All the Egyptians urged the people of Israel to get out of the land as quickly as possible, for they thought, “We will all die!” The Israelites took their bread dough before yeast was added. They wrapped their kneading boards in their cloaks and carried them on their shoulders. And the people of Israel did as Moses had instructed; they asked the Egyptians for clothing and articles of silver and gold. The LORD caused the Egyptians to look favorably on the Israelites, and they gave the Israelites whatever they asked for. So they stripped the Egyptians of their wealth! That night the people of Israel left Rameses and started for Succoth. There were about 600,000 men, plus all the women and children. A rabble of non-Israelites went with them, along with great flocks and herds of livestock.
