'Mule' in the Bible

So the servants of Absalom did to Amnon just as Absalom had commanded. Then all the king’s sons got up, and every man mounted his mule and fled.

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.
