Exodus 12:37-39

37The Israelites travelled from Rameses to Succoth. There were about 600,000 men who walked. There were also many women and children.

38Many other people also travelled with them. They had a very large number of sheep, goats and cows.

39The Israelites cooked the bread that they had brought with them from Egypt. It had no yeast in it, because they had to leave Egypt quickly. The Egyptians did not let them wait. So the Israelites did not have time to prepare any food for themselves.
