'Sake' in the Bible

For whoever wants to save his life will lose it, but whoever loses his life for my sake will find it.

For there are some eunuchs who were that way from birth, and some who were made eunuchs by others, and some who became eunuchs for the sake of the kingdom of heaven. The one who is able to accept this should accept it."

And whoever has left houses or brothers or sisters or father or mother or children or fields for my sake will receive a hundred times as much and will inherit eternal life.

And if those days had not been cut short, no one would be saved. But for the sake of the elect those days will be cut short.
