Charles Ellicott Commentary Judges 7:12

"And the Midianites and the Amalekites and all the children of the east lay along in the valley like locusts for multitude; and their camels were without number, as the sand which is upon the sea-shore for multitude." — Judges 7:12 (ASV)

Like grasshoppers. —Compare to Judges 6:5; Numbers 22:4–5.

Their camels. —Which constitute the chief wealth of Arab tribes. The multitude of camels shall cover thee, the dromedaries of Midian and Ephah (Isaiah 60:6).

As the sand. —See Joshua 11:4, and frequently in the Bible. (Isaiah 48:19, and other passages.)
