Zechariah 4:6

This is the word of the Lord unto Zerubbabel - This prince was in a trying situation, and he needed especial encouragement from God; and here it is: Not by might, (of thy own), nor by power, (authority from others), but by my Spirit - the providence, authority, power, and energy of the Most High. In this way shall my temple be built; in this way shall my Church be raised and preserved. No secular arm, no human prudence, no earthly policy, no suits at law, shall ever be used for the founding, extension, and preservation of my Church. But the spirit of the world says, "These are all means to which as we must have recourse; otherwise the cause of God may be ruined." Satan, thou liest!

Not by might . . . but by my Spirit--As the lamps burned continually, supplied with oil from a source (the living olive trees) which man did not make, so Zerubbabel need not be disheartened because of his weakness; for as the work is one to be effected by the living Spirit (compare Hag 2:5) of God, man's weakness is no obstacle, for God's might will perfect strength out of weakness (Hos 1:7; Co2 12:10; Heb 11:34). "Might and power" express human strength of every description, physical, mental, moral. Or, "might" is the strength of many (an "army"); "power," that of one man [PEMBELLUS] God can save, "whether with many, or with them that have no power" (Ch2 14:11; compare Sa1 14:6). So in the conversion of sinners (Co1 3:6; Co2 10:4). "Zerubbabel" is addressed as the chief civil authority in directing the work.

Then he answered, and spake unto me, saying,.... In great condescension, in order to instruct him into the true meaning of the vision: This is the word of the Lord unto Zerubbabel; this signifies what was said by the Lord to Zerubbabel, by some one of the prophets sent unto him: saying, Not by might, nor by power, but by my Spirit, saith the Lord of hosts: that is, that as the candlestick was supplied with oil, from the two olive trees by the side of it, without the help of any man, to pour in the oil, and trim the lamps; so the temple should be built by Zerubbabel, not through the multitude and strength of men, but through the Spirit of God, animating, exciting, encouraging, and strengthening them to go through the work. The temple was a type of the church, and Zerubbabel a type of Christ; he was so in the high esteem he was had in by the Lord; he was chosen by him; made as a signet, and was precious to him, Hag 2:23 in his titles and characters, a servant of the Lord, and governor of Judah, Hag 1:1 and in his work, in bringing the Jews out of captivity, and in rebuilding the temple: so Christ is the chosen of God, and exceeding dear and precious to him; is his righteous servant, and Governor of the church, or King of saints; and who has redeemed and delivered his people from the captivity of sin, and Satan, and the law; and is the builder of his church; who has laid the foundation of it, and will bring in the headstone; and which church is built up in all generations through the conversion of sinners; and that is done, not by external force, by carnal weapons, or moral persuasion; but by the sword of the Spirit, the word of God; and not by the power of man's free will, but by the efficacious grace of the divine Spirit: it is indeed done by power and might, but not of…

In this chapter we have another comfortable vision, which, as it was explained to the prophet, had much in it for the encouragement of the people of God in their present straits, which were so great that they thought their case helpless, that their temple could never be rebuilt nor their city replenished; and therefore the scope of the vision is to show that God would, by his own power, perfect the work, though the assistance given to it by its friends were ever so weak, and the resistance given to it by its enemies were ever so strong. Here is, I. The awakening of the prophet to observe the vision (Zac 4:1). II. The vision itself, of a candlestick with seven lamps, which were supplied with oil, and kept burning, immediately from two olive-trees that grew by it, one on either side (Zac 4:2, Zac 4:3). III. The general encouragement hereby intended to be given to the builders of the temple to go on in that good work, assuring them that it should be brought to perfection at last (Zac 4:4-10). IV. The particular explication of the vision, for the illustration of these assurances (Zac 4:11-14).

4:6 Jeshua and Zerubbabel would have success in the rebuilding of the Jerusalem Temple, not by their own force or strength, but because of the presence of God’s empowering Spirit (cp. Hag 2:4-5).
