So I answered and spake to the angel that talked with me, saying, What are these, my lord?

Jamieson-Fausset-Brown Bible Commentary

4. The prophet is instructed in the truths meant, that we may read them with the greater reverence and attention [Calvin].

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.
