'Brook' in the Bible

‘Now arise and cross the valley of the Zered.’ So we crossed the Zered Valley.

Now thirty-eight years passed from the time we left Kadesh-barnea until we crossed the Zered Valley, until that entire generation of the men of war had died from within the camp, just as the Lord had sworn to them.

I took your sinful thing, the calf which you had made, and burned it in the fire and thoroughly crushed it, grinding the metal thoroughly until it was as fine as dust; and I threw its dust into the brook that came down from the mountain.
