Luke 17:7-10 - Unworthy Servants
7 "But who of you who has a slave plowing or keeping sheep, will say to him, when he is come in from the field, 'Come at once, sit down to dinner,' 8 "and will not rather tell him, 'Get ready something for me to eat, and gird yourself to wait on me until I have eaten and drunken. Then you shall eat and drink.' 9 "Does he think the slave because he did the things that were commanded? 10 "Even so, you also, after you have done all the things that are commanded you, should say, 'We are but slaves, we have only done what it was our duty to do.'"
