Exodus 12:40-51
English Standard Version
Chapter 12
40The time that the people of Israel lived in Egypt was 430 years. 41At the end of 430 years, on that very day, all the hosts of the Lord went out from the land of Egypt. 42It 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.
43And the Lord said to Moses and Aaron, "This is the statute of the Passover: no foreigner shall eat of it,
44but every slave that is bought for money may eat of it after you have circumcised him.
45No foreigner or hired worker may eat of it.
46It shall be eaten in one house; you shall not take any of the flesh outside the house, and you shall not break any of its bones.
47All the congregation of Israel shall keep it.
48If 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.
49There shall be one law for the native and for the stranger who sojourns among you."
