Zechariah 4:8

He confirms in this passage what I lately stated — That there was no reason for the faithful to entertain doubts or to feel anxious, because they saw that the beginning of the building was mean and despised by the world; for the Lord would at length show that it was built by his sanction and command, and that it would succeed far better than all of them had thought.

But he says that the word of Jehovah came to him; (48) and yet at the end of the next verse he shows that this address came from the mouth of the angel. But it is a well-known and a common mode of speaking, that God himself is said to speak, when he employs either angels or men as his agents; for the person of the messenger lessens in no degree the reverence due to the word: the majesty, then, of God ought to remain inviolable in his word, whether brought to us by men or by angels. Now the Prophet felt assured that nothing was adduced by the angel, but what he conveyed as the minister of God.

The sum of the whole is, that the temple, though some interruptions happened, was yet so begun that its completion was at length to be expected; as God had made use of the labors of Zerubbabel, so he would not forsake the work of his hands. Since, then, God was the chief founder of the building, it could not be but that the temple would at length be completed.
