Exodus 40:36-38
36 Throughout all their journeys (A)whenever the cloud was taken up from over the tabernacle, the sons of Israel would set out;
37 but (B)if the cloud was not taken up, then they did not set out until the day when it was taken up.
38 For throughout all their journeys, (C)the cloud of the Lord was on the tabernacle by day, and there was fire in it by night, in the sight of all the house of Israel.
