'Wadis' in the Bible

“My brothers have acted deceitfully like a wadi,Like the torrents of wadis which vanish,

The wadis evaporate in warm weather;they disappear from their channels in hot weather.

and consign your gold to the dust,the gold of Ophir to the stones in the wadis,

They are living on the slopes of the wadis,among the rocks and in holes in the ground.

The lotus trees cover him with their shade, and willows that line the wadis surround him.
