Luke 12:42

And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of meat in due season? And the Lord said, Who then is. Our Lord answers the question indirectly by another question, from which they were left to gather what it would be: 'To you certainly, in the first instance, representing the "stewards" of the "household" I am about to collect, but generally to all "servants" in My house.'

That faithful and wise steward, [ oikonomos (G3623)] - 'house-steward,' whose it was to distribute to the servants their allotted portion of food. Fidelity is the first requisite in a servant; but wisdom-discretion and judgment in the exercise of his functions-is the next.

Whom his lord shall make (or will deem fit to be made) ruler over his household, to give them their portion of meat in due season? - that is, whom his lord will advance to the highest post: The reference is of course to the world to come. (See Matthew 25:21; Matthew 25:23.)
