'Pillar' in the Bible

And the Lord came down in a pillar of cloud and stood at the entrance of the tent; he then called Aaron and Miriam, and they both came forward.

then they will tell it to the inhabitants of this land. They have heard that you, Lord, are among this people, that you, Lord, are seen face to face, that your cloud stands over them, and that you go before them by day in a pillar of cloud and in a pillar of fire by night.
