Exodus 12:34-39

34The Israelites took their bread dough before yeast was added. They wrapped their kneading boards in their cloaks and carried them on their shoulders.

35And the people of Israel did as Moses had instructed; they asked the Egyptians for clothing and articles of silver and gold.

36The 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!

37That night the people of Israel left Rameses and started for Succoth. There were about 600,000 men, plus all the women and children.

38A rabble of non-Israelites went with them, along with great flocks and herds of livestock.

39For bread they baked flat cakes from the dough without yeast they had brought from Egypt. It was made without yeast because the people were driven out of Egypt in such a hurry that they had no time to prepare the bread or other food.
