'Rather' in the Bible

Actually, then, it is already a defeat for you, that you have lawsuits with one another. Why not rather be wronged? Why not rather be defrauded?

Were you called while a slave? Do not worry about it; but if you are able also to become free, rather do that.

however, in the church I desire to speak five words with my mind so that I may instruct others also, rather than ten thousand words in a tongue.
