Numbers 9:14

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 to the morning, nor break a bone of it: according to all the statute of the Passover they shall keep it.

13 But the man who is clean, and is not on a journey, and forbears to keep the Passover, that soul shall be cut off from his people; because he didn`t offer the offering of Yahweh in its appointed season, that man shall bear his sin.

14 If a stranger shall sojourn among you, and will keep the Passover to Yahweh; according to the statute of the Passover, and according to the ordinance of it, so shall he do: you shall have one statute, both for the sojourner, and for him who is born in the land.

15 On the day that the tent was reared up the cloud covered the tent, even the tent of the testimony: and at even it was on the tent as it were the appearance of fire, until morning.

16 So it was always: the cloud covered it, and the appearance of fire by night.

17 Whenever the cloud was taken up from over the Tent, then after that the children of Israel journeyed: and in the place where the cloud abode, there the children of Israel encamped.
