@Chrysostomos, I read the passage in Luke that you’re doing your research on, and I had a sudden thought. It occurred to me that the slave who said those words was accusing his master, the nobleman, of doing nothing more than what any decent nobleman is supposed to do. A nobleman delegates jobs to his underlings ~ his slaves, if you will, and the slaves carry those jobs out.
In other words, the nobleman will tell his slaves to sow, wheat, for example, and the slaves will go out and sow wheat. He’ll tell them to sow barley, and they’ll sow barley, and so on. And come harvest time, they will reap wheat and barley, and bring him the harvest. So it’s exactly as that lazy slave said: he reaps where he has not sown, but it’s not because he’s a hard man, it’s because he’s a good businessman, and because he’s doing what every good nobleman does.
So all that slave was doing was trying to give himself an excuse, albeit a very bad one, for being really lazy.
I don’t know if this means anything to you, or helps your research at all. I just thought I’d contribute what came to me as I read the passage earlier. I hadn’t ever seen it that way before now. I love it when God shows me new things from His Word!!
