Easton's Bible Dictionary
A symbol of kings descended from royal ancestors (Ezek. 17:3, 10; Dan. 11:7); of prosperity (Job 8:16); of the Messiah, a branch out of the root of the stem of Jesse (Isaiah 11:1), the "beautiful branch" (4:2), a "righteous branch" (Jeremiah 23:5), "the Branch" (Zechariah 3:8; 6:12).
Disciples are branches of the true vine (John 15:5, 6). "The branch of the terrible ones" (Isaiah 25:5) is rightly translated in the Revised Version "the song of the terrible ones," i.e., the song of victory shall be brought low by the destruction of Babylon and the return of the Jews from captivity.
