'Refrain' in the Bible

Or do only Barnabas and I not have a right to refrain from working?

For if I do wish to boast I will not be foolish, for I will be speaking the truth; but I refrain from this, so that no one will credit me with more than he sees in me or hears from me.

For,“The one who desires life, to love and see good days,Must keep his tongue from evil and his lips from speaking deceit.

and they cried out with a loud voice, saying, “How long, O Lord, holy and true, will You refrain from judging and avenging our blood on those who dwell on the earth?”
