Albert Barnes Commentary Proverbs 16:15

"In the light of the king`s countenance is life; And his favor is as a cloud of the latter rain." — Proverbs 16:15 (ASV)

The “latter rain” is that which falls in March or April just before the harvest. The “cloud” which brings it, immediately screening people from the scorching sun, and bringing plenty and blessing, is a fit type of the highest favor.
