Verse 3. - Two olive trees. These, as explained in ver. 12, discharged the oil from their fruit-bearing branches into conduits which led to the central reservoir. Without man's agency the oil is separated from the berry and keeps the lamps constantly supplied (comp. Revelation 2:4).

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.And the two olive trees by it,.... Which are explained in; see Gill on Zechariah 4:14,

one upon the right side of the bowl, and the other upon the left side thereof; in Zechariah 4:11 they are said to be on the right and left sides of the bowl or candlestick, which is the same; for the situation of them was alike, with respect to the one and the other: according to Fortunatus Scacchus, these two olive trees did not arise out of the earth, and the top of the candlestick; but out of the base of the candlestick, one on the right hand of the bowl, which hung in the middle of the candlestick; and the other on the left (o), of which he has given the figure.
