'Refrain From' in the Bible

Or is it Barnabas and I alone who have no right to refrain from working for a living?

However, if I want to boast, I will not play the fool, for it will be nothing but the truth that I will tell. But I refrain from doing so, to keep anybody, on account of the superiority of the revelations, from giving me a higher rating than my actions and teachings deserve.

and you have forgotten the encouragement which is addressed to you as sons: "My son, refrain from thinking lightly of the discipline the Lord inflicts, and giving up when you are corrected by Him.

Then in a loud voice they cried out, "Holy and true Master, how long will you refrain from charging and avenging our blood upon the inhabitants of the earth?"
