'Ploughing' in the Bible

But, who is he of you -- having a servant ploughing or feeding -- who, to him having come in out of the field, will say, Having come near, recline at meat?

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.
