37 The Israelites journeyed from Rameses to Succoth, about six hundred thousand men on foot, besides children. 38A mixed crowd also went up with them, and livestock in great numbers, both flocks and herds. 39They baked unleavened cakes of the dough that they had brought out of Egypt; it was not leavened, because they were driven out of Egypt and could not wait, nor had they prepared any provisions for themselves.
40 The time that the Israelites had lived in Egypt was four hundred and thirty years. 41At the end of four hundred and thirty years, on that very day, all the companies of the Lord went out from the land of Egypt. 42That was for the Lord a night of vigil, to bring them out of the land of Egypt. That same night is a vigil to be kept for the Lord by all the Israelites throughout their generations.
