A company of Ishmeelites. — Dothan was situated on the great caravan line by which the products of India and Western Asia were brought to Egypt. As the eastern side of Canaan is covered by the great Arabian desert, the caravans had to travel in a north-westernly direction until, having forded the Euphrates, they could strike across from Tadmor to Gilead. The route thence led them over the Jordan at Beisan, and so southward to Egypt. For “Ishmeelites,” we have “Midianites,” Heb., Medyanim, in Genesis 37:28, and Medanites, Heb., Medanim, in Genesis 37:36; but the Targum and the Syriac, instead of Ishmeelites, read Arabs. Midian was a son of Abraham by Keturah, and Ishmael was his son by Hagar. But probably these merchants were descended from neither by blood, but belonged to some branch of the Canaanites, who were the great traders of ancient times, and which Ishmael and Midian had compelled to submit to their sway. (But see Note on Genesis 25:2.) The Jewish interpreters are reduced to great straits in reconciling these names, and even assert that Joseph was sold three times. Really Ishmeelites, Midianites, and Medanites are all one and the same, if we regard them as bearing the names only politically.
It is remarkable that the Egyptians never took part in the carrying trade. Even the navigation of the Red Sea they left to the Phœnicians, Israelites, and Syrians, though Psammetichus, Pharaoh-Necho, and Apries tried to induce the Egyptians to take to maritime pursuits. Their products were corn, stuffs of byssus and other materials, and carpets; but the exportation of these goods they left to foreign traders.
Spicery, and balm, and myrrh. — The first was probably gum tragacanth, though some think that it was storax, the gum of the styrax tree (see Genesis 30:37). “Balm,” that·is, balsam, was probably the resin of the balsamodendron Gileadense, a tree which grows abundantly in Gilead, and of which the gum was greatly in use for healing wounds. “Myrrh” was certainly ladanum, the gum of the cistus rose (cistus creticus). As all these were products of Palestine valued in Egypt, Jacob included them in his present to the governor there (Genesis 43:11).
