If a foreigner dwelling among you wants to observe the Passover to the LORD, he is to do so according to the Passover statute and its ordinances. You are to apply the same statute to both the foreigner and the native of the land.’”
Jewish Publication Society of America Version (JPS1917) - Numbers 9:14 >And if a stranger shall sojourn among you, and will keep the passover unto the LORD: according to the statute of the passover, and according to the ordinance thereof, so shall he do; ye shall have one statute, both for the stranger, and for him that is born in the land.'
