'Save' in the Bible

For since in the wisdom of God the world through its wisdom did not come to know God, God was well-pleased through the foolishness of the message preached to save those who believe.

For how do you know, O wife, whether you will save your husband? Or how do you know, O husband, whether you will save your wife?

To the weak I became weak, that I might win the weak; I have become all things to all men, so that I may by all means save some.

On the first day of every week each one of you is to put aside and save, as he may prosper, so that no collections be made when I come.
