'Heavens' in the Bible

Now Absalom met the servants of David. Absalom was riding on his mule, and the mule went under the thick branches of a massive tree, and his head was caught in [the thick branches of] the tree; and he was left hanging [in midair] between heaven and earth, while the mule that had been under him kept going.

“Then the earth shook and quaked,The foundations of the heavens trembledAnd were shaken, because He was angry.

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