Lucas 17:10

Ganoon din kayo, kapag nagawa ninyo ang lahat ng bagay na iniutos sa inyo, dapat ninyong sabihin, 'Hindi kami karapat-dapat na mga lingkod. Ginawa lang namin ang dapat naming gawin.”'

So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.
