'Torrent bed' in the Bible

And for the south side southward, from Tamar as far as the waters of Meriboth-kadesh, towards the torrent bed unto the great sea, - even the south side southward.

And on the boundary of Gad, by the south side southward,,- so shall there be a boundary from Tamar unto the waters of Meribath-kadish, towards the torrent-bed, as far as the great sea.
