Numbers 9:13

10 “Tell the Israelites: ‘When any one of you or your descendants is unclean because of a dead body, or is away on a journey, he may still observe the Passover to the LORD.

11 Such people are to observe it at twilight on the fourteenth day of the second month. They are to eat the lamb, together with unleavened bread and bitter herbs;

12 they may not leave any of it until morning or break any of its bones. They must observe the Passover according to all its statutes.

13 But if a man who is ceremonially clean and is not on a journey still fails to observe the Passover, he must be cut off from his people, because he did not present the LORD’s offering at its appointed time. That man will bear the consequences of his sin.

14 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.’”

15 On the day that the tabernacle, the Tent of the Testimony, was set up, the cloud covered it and appeared like fire above the tabernacle from evening until morning.

16 It remained that way continually; the cloud would cover the tabernacle by day, and at night it would appear like fire.
