Charles Ellicott Commentary Leviticus 26:5

"And your threshing shall reach unto the vintage, and the vintage shall reach unto the sowing time; and ye shall eat your bread to the full, and dwell in your land safely." — Leviticus 26:5 (ASV)

And your threshing shall reach unto the vintage. —That is, the corn crop will be so plentiful that those employed in threshing around March will not complete it before the vintage, which was around July.

The vintage shall reach unto the sowing time. —The wine, again, will be so abundant that those engaged in gathering and pressing the grapes will not be able to finish before the sowing time arrives again, which is around October. A similar promise is made by Amos: the plowman shall overtake the reaper, and the treader of grapes him who sowed seed (Amos 9:13).
