'Cloud' in the Bible

Then the LORD will create over the entire site of Mount Zion including over those who assemble there a cloud by day

For this is what the LORD told me: "I will remain quiet and watch in my dwelling place like dazzling heat in sunshine, like a cloud of dew in the heat of harvest."

A message about Egypt: "Watch out! The LORD rides on a swift cloud, and is coming to Egypt. The idols of Egypt tremble before him, and the hearts of the Egyptians melt within them.

I've wiped away your transgressions like a cloud and your sins like mist. Return to me; because I've redeemed you.
