Deuteronomy 11:14

That I will give you the rain of your land in his due season,.... 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 "Joe 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, Ps 104:15.
