'Ploughing' in the Bible

But which of you, having a servant who is ploughing or keeping sheep, will say to him, when he comes in from the field, Come now and be seated and have a meal,

Or has he us in mind? Yes, it was said for us; because it is right for the ploughman to do his ploughing in hope, and for him who is crushing the grain to do his work hoping for a part in the fruits of it.
