'Sake' in the Bible

For we preach not ourselves, but Christ Jesus as Lord, and ourselves as your servants for Jesus'sake.

For we who live are always delivered unto death for Jesus'sake, that the life also of Jesus may be manifested in our mortal flesh.

Wherefore I take pleasure in weaknesses, in injuries, in necessities, in persecutions, in distresses, for Christ's sake: for when I am weak, then am I strong.
