Exodus 12:41 (KJV)

And the LORD gave the people favour in the sight of the Egyptians, so that they lent unto them such things as they required. And they spoiled the Egyptians.

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 dwelt in Egypt, was four hundred and thirty years.

It is a night to be much observed unto 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.

And the LORD said unto Moses and Aaron, This is the ordinance of the passover: There shall no stranger eat thereof:

But every man's servant that is bought for money, when thou hast circumcised him, then shall he eat thereof.

A foreigner and an hired servant shall not eat thereof.

In one house shall it be eaten; thou shalt not carry forth ought of the flesh abroad out of the house; neither shall ye break a bone thereof.
