Old Testament

Exodus 12:43-49
Passover Restrictions
43The Lord said to Moses and Aaron, “This is the regulation concerning the Passover: No foreigner may eat it. 44But any slave whom you have purchased may eat it if you circumcise him. 45A temporary resident or a hired servant may not eat it. 46It must be eaten inside one house. You are not to carry any of the meat outside of the house. Do not break any of its bones. 47The whole community of Israel shall do this. 48If a resident alien among you wants to observe the Passover to the Lord, every male in his household must be circumcised. Then he may take part in it. He will be treated like a native-born of the land. But no uncircumcised person may eat it. 49The same law will apply to the native-born and to the alien who resides among you.”
