The Exodus Begins
(Exodus 12:37-42)
And the children of Israel journeyed from Rameses to Succoth, about six hundred thousand on foot that were men, beside children. And a mixed multitude went up also with them; and flocks, and herds, even very much cattle. And they baked unleavened cakes of the dough which they brought forth out of Egypt, for it was not leavened; because they were thrust out of Egypt, and could not tarry, neither had they prepared for themselves any victual.
Now the sojourning of the children of Israel, who dwelled in Egypt, was four hundred and thirty years. And it came to pass at the end of the four hundred and thirty years, even the selfsame day it came to pass, that all the hosts of the LORD went out from the land of Egypt.
It is a night to be much observed to the LORD for bringing them out from the land of Egypt: this is that night of the LORD to be observed of all the children of Israel in their generations.
The Pillars of Cloud and Fire
(Exodus 13:17-22)
And it came to pass, when Pharaoh had let the people go, that God led them not through the way of the land of the Philistines, although that was near; for God said, Lest peradventure the people repent when they see war, and they return to Egypt: But God led the people about, through the way of the wilderness of the Red sea: and the children of Israel went up harnessed out of the land of Egypt. And Moses took the bones of Joseph with him: for he had straightly sworn the children of Israel, saying, God will surely visit you; and you shall carry up my bones away hence with you. And they took their journey from Succoth, and encamped in Etham, in the edge of the wilderness. And the LORD went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night: He took not away the pillar of the cloud by day, nor the pillar of fire by night, from before the people.
