Luke 17:7-10
7“But which of you, having a slave plowing or tending sheep, will say to him when he has come in from the field, ‘Come immediately and 1sit down to eat’? 8“But will he not say to him, ‘aPrepare something for me to eat, and, 1clothing yourself properly, serve me while I eat and drink; and 2afterward you 3may eat and drink’? 9“Is he grateful to the slave because he did the things which were commanded? 10“In this way, you also, when you do all the things which are commanded of you, say, ‘We are unworthy slaves; we have done only that which we ought to have done.’”
