Numbers 9:11

8 And Moses said unto them, Stay ye, that I may hear what Jehovah will command concerning you.

9 And Jehovah spake unto Moses, saying,

10 Speak unto the children of Israel, saying, If any man of you or of your generations shall be unclean by reason of a dead body, or be on a journey afar off, yet he shall keep the passover unto Jehovah.

11 In the second month on the fourteenth day at even they shall keep it; they shall eat it with unleavened bread and bitter herbs:

12 they shall leave none of it unto the morning, nor break a bone thereof: according to all the statute of the passover they shall keep it.

13 But the man that is clean, and is not on a journey, and forbeareth to keep the passover, that soul shall be cut off from his people; because he offered not the oblation of Jehovah in its appointed season, that man shall bear his sin.

14 And if a stranger shall sojourn among you, and will keep the passover unto Jehovah; 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 sojourner, and for him that is born in the land.
