'Latter Rain' in the Bible

And they wait as for rain for me, And their mouth they have opened wide As for the latter rain.

In the light of a king's face is life, And his good-will is as a cloud of the latter rain.

They asked of Jehovah rain in a time of latter rain, Jehovah is making lightnings, And rain in showers He doth give to them. To each -- the herb in the field.
