'Backs' in the Bible

[Those who] say to the tree, 'You [are] my father,' and to the stone, 'You gave birth [to] me.' For they have turned [their] {backs} to me, and not [their] faces. But in the time of their trouble they say, 'Arise and save us.'

And they have turned to me [their] backs and not [their] faces, though {I have taught them over and over again}, but they [were] not listening to accept discipline.
