Numbers 9:13-14

13But the man that is clean, and is not in a journey, and forbeareth to keep the passover, even the same soul shall be cut off from among his people: because he brought not the offering of Yhwh in his appointed season, that man shall bear his sin.

14And if a stranger shall sojourn among you, and will keep the passover unto Yhwh; according to the ordinance of the passover, and according to the manner thereof, so shall he do: ye shall have one ordinance, both for the stranger, and for him that was born in the land.
