isaiah 51:16 And I have put my words in thy mouth, and I have covered thee in the shadow of mine hand, that I may plant the heavens, and lay the foundations of the earth, and say unto Zion, Thou art my people. - Free Bible Online

      16. Addressed to Israel, embodied in "the servant of Jehovah" (Isa 42:1), Messiah, its ideal and representative Head, through whom the elect remnant is to be restored.
      put my words in thy mouth--true of Israel, the depository of true religion, but fully realized only in Israel's Head and antitype, Messiah (Isa 49:2; 50:4, 5; 59:21; De 18:18; Joh 3:34).
      covered . . . in . . . shadow of . . . hand--protected thee (see on Isa 49:2).
      plant--rather, "fix" as a tabernacle; so it ought to be rendered (Da 11:45). The "new creation," now going on in the spiritual world by the Gospel (Eph 2:10), and hereafter to be extended to the visible world, is meant (Isa 65:17; 66:22; compare Isa 13:13; 2Pe 3:10-13).
      Zion--Its restoration is a leading part in the new creation to come (Isa 65:17, 19).
