Luke 17:7-10 - Unworthy Servants
7 But who is there among you, having a servant plowing or keeping sheep, that will say, when he comes in from the field, 'Come immediately and sit down at the table,' 8 and will not rather tell him, 'Prepare my supper, clothe yourself properly, and serve me, while I eat and drink. Afterward you shall eat and drink'? 9 Does he thank that servant because he did the things that were commanded? I think not. 10 Even so you also, when you have done all the things that are commanded you, say, 'We are unworthy servants. We have done our duty.'"
