Devarim 11:13-14

And it shall come to pass, if ye shall give heed diligently unto My mitzvot which I command you today, to love HASHEM Eloheichem, and to serve Him with all your lev and with all your nefesh, That I will give you the matar (rain) of your land in its due season, the yoreh (early rain) and the malkosh (latter rain, spring rain), that thou mayest gather in thy dagan (grain), and thy tirosh (new wine), and thine yitzhar (fresh oil).
