'Thick' in the Bible

Now Absalom happened to meet the servants of David. For Absalom was riding on his mule, and the mule went under the thick branches of a great oak. And his head caught fast in the oak, so he was left hanging between heaven and earth, while the mule that was under him kept going.

“He bowed the heavens also, and came downWith thick darkness under His feet.

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