'Latter Rain' in the Bible

that He will give the rain for your land in its season, the early [fall] rain and the late [spring] rain, so that you may gather in your grain and your new wine and your [olive] oil.

“So let us know and become personally acquainted with Him; let us press on to know and understand fully the [greatness of the] Lord [to honor, heed, and deeply cherish Him].His appearing is prepared and is as certain as the dawn,And He will come to us [in salvation] like the [heavy] rain,Like the spring rain watering the earth.”

So rejoice, O children of Zion,And delight in the Lord, your God;For He has given you the early [autumn] rain in vindicationAnd He has poured down the rain for you,The early [autumn] rain and the late [spring] rain, as before.
