acts 7:58 And cast him out of the city, and stoned him: and the witnesses laid down their clothes at a young man's feet, whose name was Saul. - Free Bible Online

      58. cast him out of the city--according to Le 24:14; Nu 15:35; 1Ki 21:13; and see Heb 13:12.
      and stoned--"proceeded to stone" him. The actual stoning is recorded in Ac 7:59.
      and the witnesses--whose hands were to be first upon the criminal (De 17:7).
      laid down their clothes--their loose outer garments, to have them taken charge of.
      at a young man's feet whose name was Saul--How thrilling is this our first introduction to one to whom Christianity--whether as developed in the New Testament or as established in the world--owes more perhaps than to all the other apostles together! Here he is, having perhaps already a seat in the Sanhedrim, some thirty years of age, in the thick of this tumultuous murder of a distinguished witness for Christ, not only "consenting unto his death" (Ac 8:1), but doing his own part of the dark deed.
