Then he answered and spoke to me, saying, This is the word of the LORD to {c} Zerubbabel, saying, Not by {d} might, nor by power, but by my spirit, saith the LORD of hosts.

(c) Who was a figure of Christ, and therefore this doctrine was directed to all the Church who are his body and members.

(d) He shows that God's power alone is sufficient to preserve his Church, even though he does not use man's help to do it.

Wesley's Notes

4:6 This word - Is particularly designed to him, and in an emblem prefigures what a church it is, how precious, how full of light, how maintained by God himself. Power - Courage and valour.

King James Translators' Notes

might: or, army

Jamieson-Fausset-Brown Bible Commentary

6. 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 (Ho 1:7; 2Co 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," literally); "power," that of one man [Pembellus]. God can save, "whether with many, or with them that have no power" (2Ch 14:11; compare 1Sa 14:6). So in the conversion of sinners (1Co 3:6; 2Co 10:4). "Zerubbabel" is addressed as the chief civil authority in directing the work.

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.
