isaiah 4:2 In that day shall the branch of the LORD be beautiful and glorious, and the fruit of the earth shall be excellent and comely for them that are escaped of Israel. - Free Bible Online

      2. In contrast to those on whom vengeance falls, there is a manifestation of JesusChrist to the "escaped of Israel" in His characteristic attributes, beauty and glory, typified in Aaron's garments (Ex 28:2). Their sanctification is promised as the fruit of their being "written" in the book of life by sovereign love (Isa 4:3); the means of it are the "spirit of judgment" and that of "burning" (Isa 4:4). Their "defense" by the special presence of Jesus Christ is promised (Isa 4:5, 6).
      branch--the sprout of JEHOVAH. Messiah (Jer 23:5; 33:15; Zec 3:8; 6:12; Lu 1:78, Margin). The parallel clause does not, as MAURER objects, oppose this; for "fruit of the earth" answers to "branch"; He shall not be a dry, but a fruit-bearing branch (Isa 27:6; Eze 34:23-27). He is "of the earth" in His birth and death, while He is also "of the Lord" (Jehovah) (Joh 12:24). His name, "the Branch," chiefly regards His descent from David, when the family was low and reduced (Lu 2:4, 7, 24); a sprout with more than David's glory, springing as from a decayed tree (Isa 11:1; 53:2; Re 22:16).
      excellent-- (Heb 1:4; 8:6).
      comely-- (So 5:15, 16; Eze 16:14).
      escaped of Israel--the elect remnant (Ro 11:5); (1) in the return from Babylon; (2) in the escape from Jerusalem's destruction under Titus; (3) in the still future assault on Jerusalem, and deliverance of "the third part"; events mutually analogous, like concentric circles (Zec 12:2-10; 13:8, 9, &c.; 14:2; Eze 39:23-29; Joe 3:1-21).
