'Backs' in the Bible

They make hard laws and put great weights on men's backs; but they themselves will not put a finger to them

The God of Abraham, of Isaac, and of Jacob, the God of our fathers, has given glory to his servant Jesus; whom you gave up, turning your backs on him, when Pilate had made the decision to let him go free.

Having a form of religion, but turning their backs on the power of it: go not with these.

They say that they have knowledge of God, while by their acts they are turning their backs on him; they are hated by all, hard-hearted, and judged to be without value for any good work.
