That I will give you the rain of your land in his due season,
&c.] Such a quantity of it as the land required, a sufficiency of it to make it fruitful, and that in proper time:
the first rain and the latter rain;
the former rain in Marchesvan, the latter rain in Nisan, as the Targum of Jonathan; the first fell about our October, which was at or quickly after seedtime, to water the seed that it might take root, and grow and spring up; and the latter fell about March, a little before harvest, to ripen the corn, and swell and plump the ears of it, and make them yield more and better; (See Gill on Joel 2:23),
that thou mayest gather in thy corn, and thy wine, and thine oil;
which were the principal things the land afforded for the sustenance of men; bread corn, the stay and staff of human life, and which strengthens man's heart, and makes him fit for labour; wine, which is his drink, and makes the heart of man glad and cheerful; and oil, which in these countries was used instead of butter, and was fattening, and made the face to shine, ( Psalms 104:15 ) . The ingathering of these fruits were at different times; the barley harvest first, the wheat harvest next, and after that the vintage, and the gathering of the olives; and by means of rain in due season they were favoured with each of these.
