'Water courses' in the Bible

Gideon sent messengers throughout the hill country of Ephraim with this message: “Come down to intercept the Midianites and take control of the watercourses ahead of them as far as Beth-barah and the Jordan.” So all the men of Ephraim were called out, and they took control of the watercourses as far as Beth-barah and the Jordan.

Restore our fortunes, Lord,like watercourses in the Negev.

Streams flowing with water will be on every high mountain and every raised hill on the day of great slaughter when the towers fall.
