10. Messiah exhorts the godly after His example (Isa 49:4, 5; 42:4) when in circumstances of trial ("darkness," Isa 47:5), to trust in the arm of Jehovah alone.
      Who is, &c.--that is, Whosoever (Jud 7:3).
      obeyeth . . . servant--namely, Messiah. The godly "honor the Son, even as they honor the Father" (Joh 5:23).
      darkness-- (Mic 7:8, 9). God never had a son who was not sometimes in the dark. For even Christ, His only Son, cried out, "My God, My God, why hast Thou forsaken Me?"
      light--rather, "splendor"; bright sunshine; for the servant of God is never wholly without "light" [VITRINGA]. A godly man's way may be dark, but his end shall be peace and light. A wicked man's way may be bright, but his end shall be utter darkness (Ps 112:4; 97:11; 37:24).
      let him trust in the name of the Lord--as Messiah did (Isa 50:8, 9).
