the valley of salt: Some suppose that the Valley of Salt was south of the Dead, or Salt Sea, towards the land of Edom; and others suppose it to be the Valley of Salt, about three or four miles south-east of Palmyra, which now supplies, in a great measure, the surrounding country with salt. 2Sa 8:13; 1Ch 18:12; Psa 60:1 *title
Selah: or, the rock, Selah is generally supposed to be the same as Petra, which in Greek signifies a rock, the celebrated capital of Arabia Petrea. Strabo places it three or four days' journey from Jericho, and five days' journey from the forest of palm trees on the Red Sea. Pliny places it 600 miles from Gaza, and 125 from the Persian Gulf; but Cellarius and Reland very justly consider that the numbers have been changed, and that we ought to read 125 miles from Gaza, and 600 from the Persian Gulf. Eusebius places Beerothbenejaakan 30 miles west from Petra, and Elath ten miles east; and Burckhardt discovered the ruins of this ancient city in a valley called Wady Mousa.
