isaiah 11:10 And in that day there shall be a root of Jesse, which shall stand for an ensign of the people; to it shall the Gentiles seek: and his rest shall be glorious. - Free Bible Online

      10. root--rather, "shoot from the root" (compare Note, see on Isa 11:1; Isa 53:2; Re 5:5; 22:16).
      stand--permanently and prominently, as a banner lifted up to be the rallying point of an army or people (Isa 5:26; Joh 12:32).
      the people--peoples, answering to "the Gentiles" in the parallel member.
      to it . . . seek--diligently (Job 8:5). They shall give in their allegiance to the Divine King (Isa 2:2; 60:5; Zec 2:11). HORSLEY translates, "Of Him shall the Gentiles inquire"; namely, in a religious sense, resort as to an oracle for consultation in difficulties" (Zec 14:16). Compare Ro 15:12, which quotes this passage, "In Him shall the Gentiles trust."
      rest--resting-place (Isa 60:13; Ps 132:8, 14; Eze 43:7). The sanctuary in the temple of Jerusalem was "the resting-place of the ark and of Jehovah." So the glorious Church which is to be is described under the image of an oracle to which all nations shall resort, and which shall be filled with the visible glory of God.
