The time that the people of Israel dwelt in Egypt was four hundred and thirty years. And at the end of four hundred and thirty years, on that very day, all the hosts of the LORD went out from the land of Egypt. It was a night of watching by the LORD, to bring them out of the land of Egypt; so this same night is a night of watching kept to the LORD by all the people of Israel throughout their generations. And the LORD said to Moses and Aaron, "This is the ordinance of the passover: no foreigner shall eat of it; but every slave that is bought for money may eat of it after you have circumcised him.
No sojourner or hired servant may eat of it. In one house shall it be eaten; you shall not carry forth any of the flesh outside the house; and you shall not break a bone of it. All the congregation of Israel shall keep it. And when a stranger shall sojourn with you and would keep the passover to the LORD, let all his males be circumcised, then he may come near and keep it; he shall be as a native of the land. But no uncircumcised person shall eat of it. There shall be one law for the native and for the stranger who sojourns among you."
Thus did all the people of Israel; as the LORD commanded Moses and Aaron, so they did. And on that very day the LORD brought the people of Israel out of the land of Egypt by their hosts.
