'Rather' in the Bible

So then, you should rather forgive and comfort him, lest somehow this person should be overwhelmed by excessive sorrow.

so we are confident and prefer rather to be absent from the body and to be at home with the Lord.

And he said to me, "My grace is sufficient for you, because the power is perfected in weakness." Therefore rather I will boast most gladly in my weaknesses, in order that the power of Christ may reside in me.

For we are not able [to do] anything against the truth, but rather [only] for the truth.
