'Sake' in the Bible

Much people of the Jews therefore knew that he was there: and they came not for Jesus' sake only, but that they might see Lazarus also, whom he had raised from the dead.

Peter said unto him, Lord, why cannot I follow thee now? I will lay down my life for thy sake.

Jesus answered him, Wilt thou lay down thy life for my sake? Verily, verily, I say unto thee, The cock shall not crow, till thou hast denied me thrice.

Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake.

But all these things will they do unto you for my name's sake, because they know not him that sent me.
