Charles Ellicott Commentary Psalms 72:6

"He will come down like rain upon the mown grass, As showers that water the earth." — Psalms 72:6 (ASV)

He shall come down. —The rule of the monarch is to be beneficent as the rain refreshing the earth, and covering it with blessings as with verdure. Under a similar image, David’s last words (2 Samuel 23:4) describe a good government.

Mown grass. —The Hebrew word means “a shearing,” and is used of a fleece (Judges 6:37; as it is also translated in this verse by the Septuagint, Vulgate, and Prayer Book version), and of a hay crop (Amos 7:1). The reference here may be either to a “mown field,” on which a shower would cause fresh grass to sprout, or to meadow grass ready for mowing.
