Exodus 12:37-51

Now the sons of Israel journeyed from Rameses to Succoth, about six hundred thousand men on foot, aside from children. A mixed multitude also went up with them, along with flocks and herds, a very large number of livestock. They baked the dough which they had brought out of Egypt into cakes of unleavened bread. For it had not become leavened, since they were driven out of Egypt and could not delay, nor had they prepared any provisions for themselves. Now the time that the sons of Israel lived in Egypt was four hundred and thirty years. And at the end of four hundred and thirty years, to the very day, all the hosts of the LORD went out from the land of Egypt. It is a night to be observed for the LORD for having brought them out from the land of Egypt; this night is for the LORD, to be observed by all the sons of Israel throughout their generations. The LORD said to Moses and Aaron, “This is the ordinance of the Passover: no foreigner is to eat of it; but every man’s slave purchased with money, after you have circumcised him, then he may eat of it. A sojourner or a hired servant shall not eat of it. It is to be eaten in a single house; you are not to bring forth any of the flesh outside of the house, nor are you to break any bone of it. All the congregation of Israel are to celebrate this. But if a stranger sojourns with you, and celebrates the Passover to the LORD, let all his males be circumcised, and then let him come near to celebrate it; and he shall be like a native of the land. But no uncircumcised person may eat of it. The same law shall apply to the native as to the stranger who sojourns among you.” Then all the sons of Israel did so; they did just as the LORD had commanded Moses and Aaron. And on that same day the LORD brought the sons of Israel out of the land of Egypt by their hosts.
