Haggai 2:9

The glory of this latter house, &c. Rather, the latter glory of this house shall be greater than the former (as in R.V.); the Temple, whether as built by Solomon or now rebuilt, being regarded as one and the same house, the one only house of God. See ver. 3.

The glory here promised is first and most obviously material glory, the desirable things, the precious gifts of all nations. But it includes the spiritual glory, without which in the sight of God material splendour is worthless and unacceptable. Christ Himself, present bodily in the temple on Mount Sion during His life on earth, present spiritually in His Church now, present in the holy city, the heavenly Jerusalem, of which He is the Temple (Revelation 21:22), calling forth the spiritual worship and devotion, and as the legitimate and necessary expression of that, the wealth and treasure of all nations, is the glory here predicted. But all this is rather implied, to be discerned by the Church in the growing light of its fulfilment, than expressed, to be understood by those to whom the prophecy was first delivered.
