'Flows' in the Bible

As for your sinful thing that you had made, the calf, I took it, melted it down, ground it up until it was as fine as dust, and tossed the dust into the stream that flows down the mountain.

and the elders of that city shall bring the heifer down to a {wadi that flows with water all year} and [that] has not been plowed and has not been sown; [then] {there they shall break the neck of the heifer in the wadi}.
