Charles Ellicott Commentary Isaiah 11:10

"And it shall come to pass in that day, that the root of Jesse, that standeth for an ensign of the peoples, unto him shall the nations seek; and his resting-place shall be glorious." — Isaiah 11:10 (ASV)

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 far off upon the heights of the “holy mountain,” a signal around which the distant nations might rally as their center. 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; that is, he shall abide forever in the eternal glory which is the dwelling-place of Jehovah.
