without one coming near the other all night.

The Glory of the Lord

34Then dthe cloud covered the tent of meeting, and ethe glory of the Lord filled the tabernacle. 35And Moses was not able to enter the tent of meeting because the cloud settled on it, and the glory of the Lord filled the tabernacle. 36Throughout all their journeys, fwhenever the cloud was taken up from over the tabernacle, the people of Israel would set out. 37But gif the cloud was not taken up, then they did not set out till the day that it was taken up. 38For the cloud of the Lord was on the tabernacle by day, and fire was in it by night, in the sight of all the house of Israel throughout all their journeys.

Numbers 9:15-22

The Cloud Covering the Tabernacle

15 hOn the day that the tabernacle was set up, the cloud covered the tabernacle, the tent of the testimony. And iat evening it was over the tabernacle like the appearance of fire until morning. 16So it was always: the cloud covered it by day
Septuagint, Syriac, Vulgate; Hebrew lacks  by day
and the appearance of fire by night.
17And whenever the cloud klifted from over the tent, after that the people of Israel set out, and in the place where the cloud settled down, there the people of Israel camped. 18At the command of the Lord the people of Israel set out, and at the command of the Lord they camped. lAs long as the cloud rested over the tabernacle, they remained in camp. 19Even when the cloud continued over the tabernacle many days, the people of Israel mkept the charge of the Lord and did not set out. 20Sometimes the cloud was a few days over the tabernacle, and according to the command of the Lord they remained in camp; then according to the command of the Lord they set out. 21And sometimes the cloud remained from evening until morning. And when the cloud lifted in the morning, they set out, or if it continued for a day and a night, when the cloud lifted they set out. 22Whether it was two days, or a month, or a longer time, that the cloud continued over the tabernacle, abiding there, the people of Israel nremained in camp and did not set out, but when it lifted they set out.
