Charles Ellicott Commentary Ecclesiastes 2:6

"I made me pools of water, to water therefrom the forest where trees were reared;" — Ecclesiastes 2:6 (ASV)

Pools. In a place south of Bethlehem are still pointed out three gigantic reservoirs, known as the Pools of Solomon (Stanley’s Jewish Church, 2:197). The place is probably the same as that called Etham by Josephus in his description of Solomon’s luxury (Ant. viii. 7. 3). Josephus speaks of another Pool of Solomon (Bell. Jud. v. 4. 2). Tanks are necessary for irrigation in a land where natural streams are few and are dried up in summer. The king’s pool is mentioned in Nehemiah 2:14.
