Exodus 13:21-22

New International Version

²¹ By day the Lord went ahead^(A) of them in a pillar of cloud^(B) to guide them on their way and by night in a pillar of fire to give them light, so that they could travel by day or night. ²² Neither the pillar of cloud by day nor the pillar of fire by night left^(C) its place in front of the people.
