Genesis 46:5

5. In the wagons which Pharaoh had sent to carry him “Instead of transporting them upon camels and asses, as was usual in Palestine . The use of the Egyptian wagons, and the fact that they were sent by Pharaoh himself, evidently made a deep impression, and is emphasized by the writer . See note on Genesis 14:27 . On the direct route from Hebron to Beer-sheba the hills are too steep and sharp, and the surface is too rocky, to allow of travel on wheeled vehicles . Artificial wagon roads have never been constructed through that country. But wheels could pass from Beer-sheba east of the direct route, through the great Wady el-Khulil, and thence through the valleys to Hebron. (Robinson, 1:215.)” Newhall.
