'Back' in the Bible

and when they continued asking him, having bent himself back, he said unto them, 'The sinless of you -- let him first cast the stone at her;'

And Jesus having bent himself back, and having seen no one but the woman, said to her, 'Woman, where are those -- thine accusers? did no one pass sentence upon thee?'

'He hath blinded their eyes, and hardened their heart, that they might not see with the eyes, and understand with the heart, and turn back, and I might heal them;'

and that one having leant back on the breast of Jesus, respondeth to him, 'Sir, who is it?'
