'Thick Cloud' in the Bible

The Lord said to Moses, “Behold, I will come to you in a thick cloud, so that the people may hear when I speak with you and may believe and trust in you forever.” Then Moses repeated the words of the people to the Lord.

So it happened on the third day, when it was morning, that there were thunder and flashes of lightning, and a thick cloud was on the mountain, and a very loud blast was sounded on a ram’s horn, so that all the people who were in the camp trembled.

“He made darkness canopies around Him,A mass of waters, thick clouds of the skies.

‘Thick clouds are a hiding place for Him, so that He cannot see,And He walks on the vault (circle) of the heavens.’

“He loads the thick cloud with moisture;He disperses the cloud of His lightning.

He made darkness His hiding place (covering); His pavilion (canopy) around Him,The darkness of the waters, the thick clouds of the skies.

Out of the brightness before Him passed His thick clouds,Hailstones and coals of fire.

“I have wiped out your transgressions like a thick cloudAnd your sins like a heavy mist.Return to Me, for I have redeemed you.”

Standing before these [images] were seventy elders of the house of Israel, and among them stood Jaazaniah the son of Shaphan [the scribe], each man with his censer in his hand and a thick and fragrant cloud of incense was rising [as they prayed to these gods].
