'Cloud' in the Bible

{who goes} {before you} on your way, seeking a place for your encampment, in fire at night and in a cloud by day, to show you the way that {you should go}.

And [so] you came near, and you stood under the mountain, and the mountain [was] burning with fire up to the heart of the heaven, {dark with a very thick cloud}.

"These words Yahweh spoke to your whole assembly at the mountain from the midst of the fire and the very thick cloud [with] a loud voice, and {he did not add anything}, and [then] he wrote them on two tablets of stone and gave them to me.

And Yahweh appeared in the tent in a column of cloud, and the column of the cloud stood at the entrance of the tent.
