'Pillar' in the Bible

Now on the day that the tabernacle was erected, the cloud [of God’s presence] covered the tabernacle, that is, the tent of the Testimony; and in the evening it was over the tabernacle, appearing like [a pillar of] fire until the morning.

The Lord came down in a pillar of cloud and stood at the doorway of the tabernacle, and He called Aaron and Miriam, and they came forward.

and they will tell it to the inhabitants of this land. They have heard that You, Lord, are among these people [of Israel], that You, Lord, are seen face to face, while Your cloud stands over them; and that You go before them in a pillar of cloud by day and in a pillar of fire by night.
