| Barnes' Notes on the Bible And now - The words imply a contrast of God's dealings, rather than a contrast of time. "I am not to the remnant of this people." He had said, "I will be to them God;" so now He does not say that He will not do to them, "as in former days," but "I am not to the remnant" of this people as heretofore. He would be, as tie was in Jesus, in a new relation to them.
Gill's Exposition of the Entire BibleBut now I will not be unto the residue of this people,.... The remnant brought out of captivity, settled in the land, and now rebuilding the temple: as in the former days, saith the Lord of hosts; when they neglected the house of the Lord, caring only for their own cieled houses, Haggai 1:2.
Keil and Delitzsch Biblical Commentary on the Old TestamentBut now the Lord will act differently to His remaining people, and bless it again with a fruitful harvest of the fruits of the field and soil. כּי in Zechariah 8:12, "for," after a negative clause, "but." זרע השּׁלום, not the seed will be secure (Chald., Pesh.), but the seed of peace, viz., the vine. This is so designated, not because there is a berâkhâh in the grape (Isaiah 65:8); but because the vine can only flourish in peaceful times, and not when the land is laid waste by enemies (Koehler). On the words which follow, compare Leviticus 26:4., Psalm 67:7; Haggai 1:10; Haggai 2:19. "Future abundance will compensate for the drought and scarcity of the past" (Jerome).

Jamieson-Fausset-Brown Bible Commentary11. "But now that the temple has been built, I will not do as I had formerly done to those who returned from Babylon" [Jerome]. Henceforth I will bless you.
Matthew Henry's Concise Commentary8:9-17 Those only who lay their hands to the plough of duty, shall have them strengthened with the promises of mercy: those who avoid their fathers' faults have the curse turned into a blessing. Those who believed the promises, were to show their faith by their works, and to wait the fulfilment. When God is displeased, he can cause trade to decay, and set every man against his neighbour; but when he returns in mercy, all is happy and prosperous. Surely believers in Christ must not trifle with the exhortation to put away lying, and to speak every man peace with his neighbour, to hate what the Lord hates, and to love that wherein he delights. |
