'Save' in the Bible

For since in the wisdom of God the world by its wisdom did not know God, God was pleased to save those who believe by the foolishness of preaching.

To the weak I became weak in order to gain the weak. I have become all things to all people, so that by all means I may save some.

On the first day of the week, each of you should set aside some income and save it to the extent that God has blessed you, so that a collection will not have to be made when I come.
