Luke 17:10

So you also , when you have done all that you were commanded , say , We are unworthy servants ; we have only done what was our duty .

So you also, when you have done everything you were told to do, should say, ‘We are unworthy servants; we have only done our duty.`”

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.
