'Wadi' in the Bible

{And on the south side the border} [will run] from Tamar up to the waters [of] Meribot Kadesh [and along] the wadi to the Great Sea. And this [is] {the boundary to the south}.

and next to the territory of Gad, to [the] side of [the] south, {southward}; and [the] territory will be from Tamar [to] the waters of Meribath Kadesh, [toward] the wadi, [on] to the Great Sea.
