Luke 17: 7 - 10
7 "Will any one of you, who has a servant plowing or keeping sheep, say to him when he has come in from the field, `Come at once and sit down at table'?
8 Will he not rather say to him, `Prepare supper for me, and gird yourself and serve me, till I eat and drink; and afterward you shall 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 is commanded you, say, `We are unworthy servants; we have only done what was our duty.'"
