John Wesley on Amos 9:13

Behold the days come - Here is another promise literally of abundant plenty to the returned captives, and mystically of abundant grace poured forth in gospel - days. The plowman - Who breaks up the ground, and prepares it for sowing, shall be ready to tread on the heels of the reaper who shall have a harvest so large, that before he can gather it all in, it shall be time to plow the ground again. The treader of grapes - So great shall their vintage be that e'er the treaders of grapes can have finished their work, the seeds - man shall be sowing his seed against the next season. Shall drop - The vineyards shall be so fruitful, and new wine so plentiful as if it ran down from the mountains. Shall melt - Or, as if whole hills were melted into such liquors. If any object, it never was so: I answer, the sins of the returned captives prevented these blessings, which are promised under a tacit condition.
