"Suppose one of you has a servant that has been working in the field. The servant has been plowing the ground or caring for the sheep. When he comes in from work, what would you say to him? Would you say, 'Come in and sit down to eat'?
No! You would say to your servant, 'Prepare something for me to eat. Then get dressed and serve me. When I finish eating and drinking, then you can eat.'
It is the same with you. When you do all the things you are told to do, you should say, 'We are not worthy of any special thanks. We have only done the work we should do.'"
