'Cloud' in the Bible

And he went in flight through the air, seated on a storm-cloud: going quickly on the wings of the wind.

In the daytime he was guiding them in the cloud, and all through the night with a light of fire.

His voice came to them from the pillar of cloud; they kept his witness, and the law which he gave them.

A cloud was stretched over them for a cover; and he sent fire to give light in the night.
