      Lu 10:1-24. MISSION OF THE SEVENTY DISCIPLES, AND THEIR RETURN.

      As our Lord's end approaches, the preparations for the establishment of the coming Kingdom are quickened and extended.

      1. the Lord--a becoming title here, as this appointment was an act truly lordly [BENGEL].
      other seventy also--rather, "others (also in number), seventy"; probably with allusion to the seventy elders of Israel on whom the Spirit descended in the wilderness (Nu 11:24, 25). The mission, unlike that of the Twelve, was evidently quite temporary. All the instructions are in keeping with a brief and hasty pioneering mission, intended to supply what of general preparation for coming events the Lord's own visit afterwards to the same "cities and places" (Lu 10:1) would not, from want of time, now suffice to accomplish; whereas the instructions to the Twelve, besides embracing all those to the Seventy, contemplate world-wide and permanent effects. Accordingly, after their return from this single missionary tour, we never again read of the Seventy.
