'Thick' in the Bible

And Absalom chanced to meet the servants of David. And Absalom was riding upon his mule, and the mule went under the thick boughs of a great oak, and his head caught hold of the oak, and he was taken up between heaven and earth; and the mule that was under him went on.

He bowed the heavens also, and came down; And thick darkness was under his feet.

And he made darkness pavilions round about him, Gathering of waters, thick clouds of the skies.
