A.T. Robertson Commentary Luke 12:46

"the lord of that servant shall come in a day when he expecteth not, and in an hour when he knoweth not, and shall cut him asunder, and appoint his portion with the unfaithful." — Luke 12:46 (ASV)

Shall cut him asunder (διχοτομησε). An old and somewhat rare word from διχοτομος and that from διχα and τεμνω, to cut, to cut in two. Used literally here. In the N.T. only here and Mt 24:51.

With the unfaithful (μετα των απιστων). Not here "the unbelieving" though that is a common meaning of απιστος (α privative and πιστος, from πειθω), but the unreliable, the untrustworthy. Here Mt 24:51 has "with the hypocrites," the same point. The parallel with Mt 24:43-51 ends here. Matthew 24:51 adds the saying about the wailing and the gnashing of teeth. Clearly there Luke places the parable of the wise steward in this context while Matthew has it in the great eschatological discourse. Once again we must either think that Jesus repeated the parable or that one of the writers has misplaced it. Luke alone preserves what he gives in verses 47,48.
