Exodus 12:48-49

MSTC(i) 48 If a stranger dwell among you, and will hold Passover unto the LORD, let him circumcise all that be males, and then let him come and observe it, and be taken as one that is born in the land. No uncircumcised person shall eat thereof. 49 One manner of law shall be unto them that are born in the land, and unto the strangers that dwell among you."
