zechariah 3:8 Hear now, O Joshua the high priest, thou, and thy fellows that sit before thee: for they are men wondered at: for, behold, I will bring forth my servant the BRANCH. - Free Bible Online

      8. Hear--On account of the magnitude of what He is about to say, He at once demands solemn attention.
      thy fellows that sit before thee--thy subordinate colleagues in the priesthood; not that they were actually then sitting before him; but their usual posture in consultations was on chairs or benches before him, while he sat on an elevated seat as their president.
      they are--From speaking to Joshua He passes to speaking of him and them, in the third person, to the attendant angels (compare Zec 3:9).
      men wondered at--Hebrew, "men of wonder," that is, having a typical character (Isa 8:18; 20:3; Eze 12:11; 24:24). Joshua the high priest typifies Messiah, as Joshua's "fellows" typify believers whom Messiah admits to share His Priesthood (1Pe 2:5; Re 5:10). This, its typical character, then, is a pledge to assure the desponding Jews that the priesthood shall be preserved till the great Antitype comes. There may be also an indirect reproof of the unbelief of the multitude who "wonder" at God's servants and even at God's Son incredulously (Ps 71:7; Isa 8:18; 53:1, &c.).
      behold--marking the greatness of what follows.
      my servant--the characteristic title of Messiah (Isa 42:1; 49:3; 50:10; 52:13; 53:11; Eze 34:23, 24).
      the Branch--Messiah, a tender branch from the almost extinct royal line of David (Zec 6:12; Isa 4:2; 11:1; Jer 23:5; 33:15). Lu 1:78, where for "day spring," "branch" may be substituted (Mal 4:2, however, favors English Version). The reference cannot be to Zerubbabel (as GROTIUS thinks), for he was then in the full discharge of his office, whereas "the Branch" here is regarded as future.
