Numbers 9:15-23 Revised Standard Version (RSV)
The Cloud and the Fire
15 On the day that the tabernacle was set up, the cloud covered the tabernacle, the tent of the testimony; and at evening it was over the tabernacle like the appearance of fire until morning. 16 So it was continually; the cloud covered it by day[a] and the appearance of fire by night. 17 And whenever the cloud was taken up 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 encamped. 18 At the command of the Lord the people of Israel set out, and at the command of the Lord they encamped; as long as the cloud rested over the tabernacle, they remained in camp. 19 Even when the cloud continued over the tabernacle many days, the people of Israel kept the charge of the Lord, and did not set out. 20 Sometimes 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. 21 And sometimes the cloud remained from evening until morning; and when the cloud was taken up in the morning, they set out, or if it continued for a day and a night, when the cloud was taken up they set out. 22 Whether it was two days, or a month, or a longer time, that the cloud continued over the tabernacle, abiding there, the people of Israel remained in camp and did not set out; but when it was taken up they set out. 23 At the command of the Lord they encamped, and at the command of the Lord they set out; they kept the charge of the Lord, at the command of the Lord by Moses.
Numbers 10:29-36 Revised Standard Version (RSV)
29 And Moses said to Hobab the son of Reu′el the Mid′ianite, Moses’ father-in-law, “We are setting out for the place of which the Lord said, ‘I will give it to you’; come with us, and we will do you good; for the Lord has promised good to Israel.” 30 But he said to him, “I will not go; I will depart to my own land and to my kindred.” 31 And he said, “Do not leave us, I pray you, for you know how we are to encamp in the wilderness, and you will serve as eyes for us. 32 And if you go with us, whatever good the Lord will do to us, the same will we do to you.”
33 So they set out from the mount of the Lord three days’ journey; and the ark of the covenant of the Lord went before them three days’ journey, to seek out a resting place for them. 34 And the cloud of the Lord was over them by day, whenever they set out from the camp.
35 And whenever the ark set out, Moses said, “Arise, O Lord, and let thy enemies be scattered; and let them that hate thee flee before thee.” 36 And when it rested, he said, “Return, O Lord, to the ten thousand thousands of Israel.”
