Exodus 12:37-42 - The Israelites Leave Egypt
37 The Israelites left Rameses to go to Succoth. There were about six hundred thousand men on foot, plus all the women and children. 38 Many other people also went with them, along with large numbers of sheep, goats, and cattle. 39 With the dough they had brought from Egypt, they baked round, flat bread. The dough had not risen because they had been thrown out of Egypt and had no time to prepare food for the trip.
40 The Israelites had been living in Egypt for four hundred and thirty years. 41 After exactly four hundred and thirty years all of Jehovah's people left Egypt in organized family groups. 42 It is a night to be observed for Jehovah for having brought them out from the land of Egypt. This night is for Jehovah and should be observed by all the sons of Israel throughout their generations.
