C. F. Keil and Franz Delitzsch on Zechariah 8:11-12

Zec 8:11-12

But 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 Zec 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 (Isa 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 Lev 26:4., Psa 67:7; Hag 1:10; Hag 2:19. “Future abundance will compensate for the drought and scarcity of the past” (Jerome).
