'Backs' in the Bible

But they were hard-hearted, and went against your authority, turning their backs on your law, and putting to death your prophets, who gave witness against them with the purpose of turning them back again to you, and they did much to make you angry.

And gave witness against them so that you might make them come back again to your law: but their hearts were lifted up, and they gave no attention to your orders and went against your decisions (which, if a man keeps them, will be life to him), and turning their backs on you, made their necks stiff and did not give ear.
