Numbers 9:18

14“‘If a foreigner lives among you and desires to keep the Passover to the LORD, then he shall do so according to the statute of the Passover, and according to its ordinance. You shall have one statute, both for the foreigner and for him who is born in the land.’”

15On the day that the tabernacle was raised up, the cloud covered the tabernacle, even the Tent of the Testimony. At evening it was over the tabernacle, as it were the appearance of fire, until morning.

16So it was continually. The cloud covered it, and the appearance of fire by night.

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

18At the commandment of the LORD, the children of Israel traveled, and at the commandment of the LORD they encamped. As long as the cloud remained on the tabernacle they remained encamped.

19When the cloud stayed on the tabernacle many days, then the children of Israel kept the LORD’s command, and didn’t travel.

20Sometimes the cloud was a few days on the tabernacle; then according to the commandment of the LORD they remained encamped, and according to the commandment of the LORD they traveled.

21Sometimes the cloud was from evening until morning; and when the cloud was taken up in the morning, they traveled; or by day and by night, when the cloud was taken up, they traveled.

22Whether it was two days, or a month, or a year that the cloud stayed on the tabernacle, remaining on it, the children of Israel remained encamped, and didn’t travel; but when it was taken up, they traveled.
