The {e} silver is mine, and the gold is mine, saith the LORD of hosts.

(e) Therefore when his time comes he can make all the treasures of the world to serve his purpose: but the glory of this second Temple does not consist of material things, neither can it be built.

Wesley's Notes

2:8 The silver - The treasures of both: doubt not therefore but I will give enough to build this house.

Jamieson-Fausset-Brown Bible Commentary

8. The silver is mine-(Job 41:11; Ps 50:12). Ye are disappointed at the absence of these precious metals in the adorning of this temple, as compared with the first temple: If I pleased I could adorn this temple with them, but I will adorn it with a "glory" (Hag 2:7, 9) far more precious; namely, with the presence of My divine Son in His veiled glory first, and at His second coming with His revealed glory, accompanied with outward adornment of gold and silver, of which the golden covering within and without put on by Herod is the type. Then shall the nations bring offerings of those precious metals which ye now miss so much (Isa 2:3; 60:3, 6, 7; Eze 43:2, 4, 5; 44:4). The heavenly Jerusalem shall be similarly adorned, but shall need "no temple" (Re 21:10-22). Compare 1Co 3:12, where gold and silver represent the most precious things (Zec 2:5). The inward glory of New Testament redemption far exceeds the outward glory of the Old Testament dispensation. So, in the case of the individual poor believer, God, if He pleased, could bestow gold and silver, but He bestows far better treasures, the possession of which might be endangered by that of the former (Jas 2:5).

Matthew Henry's Concise Commentary

2:1-9 Those who are hearty in the Lord's service shall receive encouragement to proceed. But they could not build such a temple then, as Solomon built. Though our gracious God is pleased if we do as well as we can in his service, yet our proud hearts will scarcely let us be pleased, unless we do as well as others, whose abilities are far beyond ours. Encouragement is given the Jews to go on in the work notwithstanding. They have God with them, his Spirit and his special presence. Though he chastens their transgressions, his faithfulness does not fail. The Spirit still remained among them. And they shall have the Messiah among them shortly; He that should come. Convulsions and changes would take place in the Jewish church and state, but first should come great revolutions and commotions among the nations. He shall come, as the Desire of all nations; desirable to all nations, for in him shall all the earth be blessed with the best of blessings; long expected and desired by all believers. The house they were building should be filled with glory, very far beyond Solomon's temple. This house shall be filled with glory of another nature. If we have silver and gold, we must serve and honour God with it, for the property is his. If we have not silver and gold, we must honour him with such as we have, and he will accept us. Let them be comforted that the glory of this latter house shall be greater than that of the former, in what would be beyond all the glories of the first house, the presence of the Messiah, the Son of God, the Lord of glory, personally, and in human nature. Nothing but the presence of the Son of God, in human form and nature, could fulfil this. Jesus is the Christ, is He that should come, and we are to look for no other. This prophecy alone is enough to silence the Jews, and condemn their obstinate rejection of Him, concerning whom all their prophets spake. If God be with us, peace is with us. But the Jews under the latter temple had much trouble; but this promise is fulfilled in that spiritual peace which Jesus Christ has by his blood purchased for all believers. All changes shall make way for Christ to be desired and valued by all nations. And the Jews shall have their eyes opened to behold how precious He is, whom they have hitherto rejected.
