Who art thou, O {e} great mountain? before Zerubbabel thou shalt become a plain: and {f} he shall bring forth its headstone with shoutings, crying, Grace, grace to it.

(e) He compares the power of the adversaries to a great mountain, who thought the Jews were nothing with regard to them, and would have hindered Zerubbabel, who represented Christ, whom the enemies daily labour to stop in the building of his spiritual Temple, but all in vain.

(f) Though the enemies think to stop this building, yet Zerubbabel will lay the highest stone of it, and bring it to perfection, so that all the godly will rejoice, and pray to God that he would continue his grace and favour toward the Temple.

Wesley's Notes

4:7 O great mountain - All opposers put together. Become a plain - Thou shalt sink into nothing. The head stone - Shall assist at the laying of the finishing stone, as he assisted when the foundation stone was laid. Grace, grace - Wishing all prosperity, and a long continuance of it, to the temple and those that are to worship God therein. As the free favour of God began, and finished, may the same ever dwell in it and replenish it.

Jamieson-Fausset-Brown Bible Commentary

7. All mountain-like obstacles (Isa 40:4; 49:11) in Zerubbabel's way shall be removed, so that the crowning top-stone shall be put on, and the completion of the work be acknowledged as wholly of "grace." Antitypically, the antichristian last foe of Israel, the obstacle preventing her establishment in Palestine, about to be crushed before Messiah, is probably meant (Jer 51:25; Da 2:34, 44; Mt 21:44).

bring forth the head-stone-Primarily, bring it forth from the place where it was chiselled and give it to the workmen to put on the top of the building. It was customary for chief magistrates to lay the foundation, and also the crowning top-stone (compare Ezr 3:10). Antitypically, the reference is to the time when the full number of the spiritual Church shall be completed, and also when "all Israel shall be saved" (compare Ro 11:26; Heb 11:40; 12:22, 23; Re 7:4-9).

Grace, grace-The repetition expresses, Grace from first to last (Isa 26:3, Margin). Thus the Jews are urged to pray perseveringly and earnestly that the same grace which completed it may always preserve it. "Shoutings" of acclamation accompanied the foundation of the literal temple (Ezr 3:11, 13). So shoutings of "Hosanna" greeted the Saviour in entering Jerusalem (Mt 21:9), when about to complete the purchase of salvation by His death: His Body being the second temple, or place of God's inhabitation (Joh 2:20, 21). So when the full number of the saints and of Israel is complete, and God shall say, "It is done," then again shall "a great voice of much people in heaven" attribute all to the "grace" of God, saying, "Alleluia! Salvation, and glory, and honor, and power, unto the Lord our God" (Re 19:1, 6). Ps 118:22 regards Him as "the head-stone of the corner," that is, the foundation-stone. Compare the angels acclamations at His birth, Lu 2:14. Here it is the top-stone. Messiah is not only the "Author," but also the Finisher (Heb 12:2). "Grace" is ascribed "unto it," that is, the stone, Messiah. Hence the benediction begins, "The grace of the Lord Jesus Christ" (2Co 13:14).

Matthew Henry's Concise Commentary

4:1-7 The prophet's spirit was willing to attend, but the flesh was weak. We should beg of God that, whenever he speaks to us, he would awaken us, and we should then stir up ourselves. The church is a golden candlestick, or lamp-bearer, set up for enlightening this dark world, and holding forth the light of Divine revelation. Two olive trees were seen, one on each side the candlestick, from which oil flowed into the bowl without ceasing. God brings to pass his gracious purposes concerning his church, without any art or labour of man; sometimes he makes use of his instruments, yet he needs them not. This represented the abundance of Divine grace, for the enlightening and making holy the ministers and members of the church, and which cannot be procured or prevented by any human power. The vision assures us that the good work of building the temple, should be brought to a happy end. The difficulty is represented as a great mountain. But all difficulties shall vanish, and all the objections be got over. Faith will remove mountains, and make them plains. Christ is our Zerubbabel; mountains of difficulty were in the way of his undertaking, but nothing is too hard for him. What comes from the grace of God, may, in faith, be committed to the grace of God, for he will not forsake the work of his own hands.
