The first two slaves generate commentary boilerplate and unremarkable. Different abilities, different productivities, both doing their best, both praised. But the third slave.....
“But another one came, saying, ‘Lord, here is your mina that I kept hidden away in a cloth. You see, I was in fear of you, because you are a harsh man; you take what you did not deposit, and you reap what you did not sow.’ He said to him, ‘By your own words I judge you, wicked slave. You knew, did you, that I am a harsh man, taking what I did not deposit and reaping what I did not sow? So why did you not put my money in a bank? Then on my coming, I would have collected it with interest.’” (Luke 19:20-23)
What I like is that the third slave of Luke 19 approaches the master and hasn’t done a thing with his mina; he has hidden it in a cloth and offers the explanation that he knew his master was a harsh man, taking where he did not deposit and reaping where he did not sow.
The Master does not deny it! That 3rd slave may have a bad attitude, but he does not deny it. He does reap where he does not sow. He does reap disciples where he did not directly make them himself. Get used to it.
It is a bad attitude that the slave had but it appears that the master could have worked with it—‘just put it in the bank and I get the interest’ he says. Who knows where the slave picked up his rotten attitude?—maybe he was wronged somewhere In the past. It doesn’t matter. Just deliver the interest and the master can work with it. Depositing it in the bank is not much, but it appears that the Master could have worked with it.
The parallel illustration at Matt 25 has that “wicked slave” burying his master’s talent in the ground, working up a sweat so as to thwart his Master’s will. Why would anyone do that?
