Exodus 12:44-49

44but every man’s slave who is bought with money, after you have circumcised him, then he may eat it.

45No stranger (temporary resident, foreigner) or hired servant shall eat it.

46It is to be eaten inside one house; you shall not take any of the meat outside the house, nor shall you break any of its bones.

47The entire congregation of Israel shall keep and celebrate it.

48If a stranger living temporarily among you wishes to celebrate the Passover to the Lord, all his males must be circumcised, and then he may participate and celebrate it like one that is born in the land. But no uncircumcised person may eat it.

49The same law shall apply to the native-born and to the stranger who lives temporarily among you.”
