'Wadi' in the Bible
And they {set out} and {went up into the hill country}, and they went up to the wadi of Eschol, and they spied out [the land].
So [now] arise and cross over the wadi of Zered yourselves; and [so] we crossed the wadi of Zered.
Now the {length of time} that we had traveled from Kadesh Barnea until [the time when] we crossed the wadi of Zered [was] thirty-eight years, until the perishing of all of that generation; [that is], the men of war from the midst of the camp as Yahweh had sworn to them.
Arise, set out and cross [over] the wadi of Arnon. Look! I have given Sihon the Amorite, the king of Heshbon, and his land into your hand; begin to take possession of [it], and engage with him in battle.
From Aroer, which [is] on the edge of the wadi of Arnon and the city that [was] in the wadi on up to Gilead, [there] was not a city that was inaccessible to us; Yahweh our God gave {everything} {to us}.
"And so we took at that time the land from {the control of} [the] two kings of the Amorites who [were] {on the other side of the Jordan}, from the wadi of Arnon up to {Mount Hermon}.
And [so] we took possession of this land at that time, from Aroer, which [is] on the [edge of the] wadi of Arnon, and [also] half of the hill country of Gilead and its towns I gave to the Reubenites and to the Gadites.
And to the Reubenites and to the Gadites I gave, from Gilead up to the wadi of Arnon, the middle of the wadi [as a] boundary and up to the Jabbok {River}, the boundary of the {Ammonites}.
from Aroer, which [is] on the bank of the wadi of Arnon and as far as Mount Sirion; that [is], Hermon,
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}.
And all of the elders of that city nearest to the slain person shall wash their hands over the heifer [with] the broken neck in the wadi.
