In that day there shall be a root of Jesse... — The “root,” as in Isaiah 53:2; Deuteronomy 29:18, is the same as the “rod” and “branch” growing from the root in Isaiah 11:1. The new shoot of the fallen tree of Jesse is to grow up like a stately palm, seen afar off upon the heights of the “holy mountain,” a signal round which the distant nations might rally as their centre. So the name of “the root of David” is applied to the glorified Christ in Revelation 5:5; Revelation 22:16. The word for “seek” implies, as in Isaiah 8:19; Isaiah 19:3; Isaiah 55:6, the special seeking for wisdom and illumination.
His rest shall be glorious. — Better, his resting-place shall be glory; i.e., he shall abide evermore in the eternal glory which is the dwelling-place of Jehovah.
