'Backs' in the Bible

Then Naaman said, If you will not, then let there be given to your servant as much earth as two beasts are able to take on their backs; because from now on, your servant will make no offering or burned offering to other gods, but only to the Lord.

So Hazael went to see him, taking with him forty camels with offerings on their backs of every sort of good thing from Damascus; and when he came before him, he said, Your son Ben-hadad, king of Aram, has sent me to you, saying, Will I get better from this disease?

And turning their backs on all the orders which the Lord had given them, they made for themselves images of metal, and the image of Asherah, worshipping all the stars of heaven and becoming servants to Baal.
