Nehemiah 9:18-19

Even after they had cast an image of a calf for themselves and said, “This is your god who brought you out of Egypt,” and they had committed terrible blasphemies, you did not abandon them in the wilderness because of your great compassion. During the day the pillar of cloud never turned away from them, guiding them on their journey. And during the night the pillar of fire illuminated the way they should go.
