Leviticus 26:4

“Then I will give you rain in due season, etc.] The former and latter rain, in the two seasons of the year in which rain usually fell, and the Scriptures frequently speak of; and when the land of Israel, which required rain, not being watered with a river, as Egypt, was blessed with it; the one was at the sowing of their seed, or a little after it, and the other a little before harvest; and when it was had in those times it was had in due season, and hence the word is in the plural number, “your rains” f903; unless showers of rain are meant: to encourage to keep the commands of God, promises of many outward good things are made; and this is the first, being a principal blessing, and which…”
