Commentators generally take it for granted that the "root of Jesse" in this verse is the same as the "rod out of the Stem of Jesse" in verse 1. They apply both the "rod out of the stem" and the "root" to the Messiah. But in verses 4-9 the Millennium is clearly introduced, and in this verse we read that the root of Jesse stands for an "ensign"; that is, a banner around which even the Gentiles will gather. We read that the "rest" of the Messiah, that is, his resting place, the temple (1 Chron. 28:2), will be "glorious," and in the next verse we are told that the gathering of the remnant of Israel and Judah has begun for a second time. All of which seems to me to point to the time in which we are now living, and the preparations now being made for the Millennium, through the Church of Jesus Christ of Latter-day Saints.
