Zechariah 8:9

Let - To hinder or obstruct.

By the mouth of the prophets - The day or time of the foundation was about two years before, as this discourse of the prophet was in the fourth year of Darius. After this God raised up prophets among them.

Let your hands be strong - The fulfillment of God's former promises are the earnest of the future; His former providences, of those to come. Having then those great promises for the time to come, they were to be earnest in whatever meantime God gave them to do. He speaks to them, "as hearing in these days," that is, that fourth year of Darius in which they apparently were, "these words from the mouth of the prophets, which were in the day when the foundation of the house of the Lord was laid, the temple, that it might be built."

Now he speaks to the Jews, but not so as to seem to forget what he had said before. He would say, Ye who hear the words, which in those days when the temple was founded, Haggai and Zechariah spake, be strong and proceed to the work which ye began of fulfilling the will of the Lord in the building of the temple, and in keeping from the sins, in which ye were before entangled. For as, before ye began to build the temple, ye were afflicted with many calamities, but after ye had begun, all things went well with you, as Haggai said, "so, if you cultivate piety and do not depart from God, ye shall enjoy great abundance of spiritual good" Haggai 2:15-19. Osorius: "The memory of past calamity made the then tranquillity much sweeter, and stirred the mind to greater thanksgiving. He set forth then the grief of those times when he says;"
