I. THIS TITLE IMPLIES THE ENTIRE IDENTIFICATION OF CHRIST WITH HUMANITY. The certainty of final triumph for humanity rests on the fact of its vital union with Christ.
II. THE TITLE CONNECTS HIM WITH THE STREAM OF HUMAN HISTORY. A mysterious consciousness belonged to many of the members of His house and line. Some of them were prophets, and from them sounded out on the youth of the world sayings pregnant with distant meaning. They themselves were types, signs, representatives of Christ, until He Himself should appear.
III. THE TITLE ESTABLISHES A UNITY IN THE HISTORY OF THE JEWISH NATION. Since, in the Divine counsels, it had been determined that the Redeemer should arise out of the bosom of humanity, some line must be necessarily selected as that of His descent. The line is that of the royal David, and this is the clue by which to traverse the maze of the world's history until the incarnation.
IV. THE TITLE EMBODIES A REFERENCE TO THE KINGLY OFFICE OF CHRIST. The favourite representation of the prophets is that of the King, whose reign shall be in peace, in truth, in equity, in righteousness for ever and ever (Psalm 122; Isaiah 2:4; 42:1-4; 52:13-15, 16; Daniel 2:44; Daniel 7:13, 14; Micah 5:1-4).
V. THE TITLE ALLUDES TO THE VIGOROUS GROWTH AND SURPASSING GREATNESS OF THE KINGDOM OF CHRIST. The word "root" evidently refers to the prophecy in Isaiah 1:1-10 (see also Isaiah 4:2; Jeremiah 23:5; Zechariah 3:8; Zechariah 6:12). Not the actual root of the tree is meant, but the scion or sucker, which sprouts from the decaying root. At the advent of the Saviour the kingdom of David was indeed like the fallen trunk of a noble tree. A foreign people treads on Judea's soil, and bows a once powerful nation beneath its yoke. Yet behold the vigorous sprout which comes forth out of this decayed root!
(E. Johnson, B. A.)
