Jamieson, Fausset and Brown on Haggai 2:9

9. The glory of this latter house ... greater than of the former--namely, through the presence of Messiah, in (whose) face is given the light of the knowledge of the glory of God (2Co 4:6; compare He 1:2), and who said of Himself, "in this place is one greater than the temple" (Mt 12:6), and who "sat daily teaching in it" (Mt 26:55). Though Zerubbabel's temple was taken down to the foundations when Herod rebuilt the temple, the latter was considered, in a religious point of view, as not a third temple, but virtually the second temple.

in this place ... peace--namely, at Jerusalem, the metropolis of the kingdom of God, whose seat was the temple: where Messiah "made peace through the blood of His cross" (Col 1:20). Thus the "glory" consists in this "peace." This peace begins by the removal of the difficulty in the way of the just God accepting the guilty (Psa 85:8, 10; Is 9:6, 7; 53:5; Zec 6:13; 2Co 5:18, 19); then it creates peace in the sinner's own heart (Is 57:19; Ac 10:36; Ro 5:1; 14:17; Ep 2:13-17; Php 4:7); then peace in the whole earth (Mi 5:5; Lu 2:14). First peace between God and man, then between man and God, then between man and man (Is 2:4; Ho 2:18; Zec 9:10). As "Shiloh" (Ge 49:10) means peace, this verse confirms the view that Hag 2:7, "the desire of all nations," refers to Shiloh or Messiah, foretold in Ge 49:10.
