Exodus 12:31-39

He summoned Moses and Aaron during the night and said, “Get out immediately from among my people, both you and the Israelites, and go, worship the LORD as you have said. Take even your flocks and your herds as you asked and leave, and also bless me.” Now the Egyptians pressured the people in order to send them quickly out of the country, for they said, “We’re all going to die! ”  So the people took their dough before it was leavened, with their kneading bowls wrapped up in their clothes on their shoulders. The Israelites acted on Moses’s word and asked the Egyptians for silver and gold items and for clothing.  And the LORD gave the people such favor with the Egyptians that they gave them what they requested. In this way they plundered the Egyptians. The Israelites traveled from Rameses to Succoth,  about six hundred thousand  able-bodied men on foot, besides their families. A mixed crowd also went up with them, along with a huge number of livestock, both flocks and herds. The people baked the dough they had brought out of Egypt into unleavened loaves, since it had no yeast; for when they were driven  out of Egypt, they could not delay and had not prepared provisions for themselves.
