Nehemiah 9:12; Nehemiah 9:19

12 By day you led them with a pillar of cloud, and by night with a pillar of fire to give them light on the way they were to take.

19 “Because of your great compassion you did not abandon them in the wilderness. By day the pillar of cloud did not fail to guide them on their path, nor the pillar of fire by night to shine on the way they were to take.
