Charles Ellicott Commentary Psalms 65:12

"They drop upon the pastures of the wilderness; And the hills are girded with joy." — Psalms 65:12 (ASV)

They drop upon. — Supply “fatness” from the last verse.

And the little hills. — A marginal note offers further comment. The freshness and beauty of plant life, which suddenly, as by a miracle, in Eastern lands clothes the hillsides, resembles a beautiful mantle thrown around their shoulders, as if to deck them for some festival.
