Whatever the Lord commands we must do.

And they kept the Passover on the fourteenth day of the first month, at twilight, in the Wilderness of Sinai; according to all that the Lord commanded Moses, so the children of Israel did. Now on the day that the tabernacle was raised up, the cloud covered the tabernacle, the tent of the Testimony; from evening until morning it was above the tabernacle like the appearance of fire. So it was always: the cloud covered it by day, and the appearance of fire by night. Whenever the cloud was taken up from above the tabernacle, after that the children of Israel would journey; and in the place where the cloud settled, there the children of Israel would pitch their tents. At the command of the Lord the children of Israel would journey, and at the command of the Lord they would camp; as long as the cloud stayed above the tabernacle they remained encamped. Even when the cloud continued long, many days above the tabernacle, the children of Israel kept the charge of the Lord and did not journey. So it was, when the cloud was above the tabernacle a few days: according to the command of the Lord they would remain encamped, and according to the command of the Lord they would journey. So it was, when the cloud remained only from evening until morning: when the cloud was taken up in the morning, then they would journey; whether by day or by night, whenever the cloud was taken up, they would journey. Whether it was two days, a month, or a year that the cloud remained above the tabernacle, the children of Israel would remain encamped and not journey; but when it was taken up, they would journey. At the command of the Lord they remained encamped, and at the command of the Lord they journeyed; they kept the charge of the Lord, at the command of the Lord by the hand of Moses.
