Numbers 9:15-23 - The Cloud And The Fire
15 And on the day that the tabernacle was raised up, the cloud covered the tabernacle over the tent of the testimony; and in the evening there was upon the tabernacle, as it were, the appearance of fire until the morning. 16 So it was always: the cloud covered it, and the appearance of fire by night. 17 And when the cloud was taken up from the tabernacle, then after that the sons of Israel journeyed; and in the place where the cloud abode, there the sons of Israel pitched their tents. 18 At the commandment of the LORD the sons of Israel journeyed, and at the commandment of the LORD they pitched camp; as long as the cloud abode upon the tabernacle, they rested.
19 And when the cloud tarried long upon the tabernacle many days, then the sons of Israel kept the charge of the LORD and did not journey. 20 And so it was, when the cloud was a determined number of days upon the tabernacle, according to the commandment of the LORD they camped, and according to the commandment of the LORD they journeyed. 21 And so it was that when the cloud remained from evening unto the morning, and in the morning the cloud was taken up, then they journeyed; or if it had remained during the day and the cloud was taken up by night, they journeyed. 22 Or if it was two days or a month or a year that the cloud tarried upon the tabernacle, remaining thereon, the sons of Israel camped and did not journey; but when it was taken up, they journeyed. 23 At the commandment of the LORD they camped, and at the commandment of the LORD they journeyed, keeping the charge of the LORD, as the LORD had said by the hand of Moses.
