Luke 17:7-10 (ESV)

7 “Will any one of you who has a servant[a] plowing or keeping sheep say to him when he has come in from the field, ‘Come at once and recline at table’? 8 Will he not rather say to him, ‘Prepare supper for me, and dress properly,[b] and serve me while I eat and drink, and afterward you will eat and drink’? 9 Does he thank the servant because he did what was commanded? 10 So you also, when you have done all that you were commanded, say, ‘We are unworthy servants;[c] we have only done what was our duty.’”
