Exodus 12:44-48

44but every man’s servant that is bought for money, after you have circumcised him, may eat it.

45Nor should a visitor or hired servant eat it.

46It is to be eaten inside a single house. You are not to carry the meat out of the house, nor are you to break any of its bones.

47All the congregation of Israel must keep it.

48But if an outsider dwells with you, who would keep the Passover for Adonai, all his males must be circumcised. Then let him draw near and keep it. He will be like one who is native to the land. But no uncircumcised person may eat from it.
