The name of Ishmael is met with in Babylonian contracts of the age of Abraham. It is a name which belongs to Canaan rather than to Babylonia or Arabia. The Ishmaelite tribes, in fact, spoke dialects in which Canaanitish and Arabic elements were mingled together. They are the dialects we term Aramaic, and represent a mixture of Arabic with Canaanitish or Hebrew. As we go northwards into Syria the Canaanitish element predominates; southward the Arabic element is the more pronounced.
The Ishmaelites were merchants and traders. They lived on the caravan-road which brought the spices of southern Arabia to Canaan and Egypt, and the trade was largely in their hands. In the history of Joseph we hear of them carrying the balm of Gilead and the myrrh of the south on their camels to Egypt, and in the second century before the Christian era the merchant princes of Petra made their capital one of the wealthiest of Oriental cities. It was not until 105 A.D. that the Nabathean state was conquered by Rome, and the Ishmaelites of northern Arabia transformed into Roman subjects. They have left their tombs and inscriptions among the rocks of Petra, while the cliffs of the Sinaitic Peninsula are covered with the scrawls of Nabathean travellers.
Southward of the Ishmaelites came the Midianites. Midianites and Ishmaelites were alike of the same blood. Both traced their descent from Abraham; it was only on the side of the mother that their origin was different. While the Ishmaelites claimed connection with Egypt, the Midianites were more purely Arabic in race. The name of Keturah their ancestress means "incense," and points to the incense-bearing lands of the south. Midian was properly the district which stretched along the western coast of the Gulf of Aqaba towards Mecca, if not towards Yemen. But Midianite tribes had also pushed northwards and mingled with the descendants of Ishmael. "Ishmaelites" and "Midianites" seem convertible terms in the story of Joseph, and the Midianites who swarmed into the north of Israel in the days of Gideon, along with the Amalekites and "the children of the East," must have been as much Ishmaelite as Midianite in descent.
Between the Midianites and the Israelitish fugitives from Egypt there had been close affinity. Moses had found a refuge in Midian, and his wife and children were Midianite in race. His father-in-law, "the priest of Midian," had visited him under the shadow of Sinai, and had given him his first lessons in political organisation. A Midianite remained to guide the Israelites through the wilderness, and the Kenites, who took part with the tribe of Judah in the conquest of Canaan, appear to have migrated from Midian. It was not until just before the invasion of Palestine that the old bonds of friendship and mixture between Israel and Midian were broken asunder. Midianite hosts had overrun the land of Moab as at a later time they overran the land of Israel, and the Israelites had forsaken Yahveh for the worship of the Midianite Baal-Peor. This was the result of intermarriage; the Israelites had taken Midianite wives and conformed to the licentious rites of a Midianite god.
Israel, however, was saved by its Levite priests. They rallied round Yahveh and Moses, and in the struggle that ensued the forces on the side of the national God proved the stronger. The Midianitish faction was annihilated, its leaders put to death, and the Midianites themselves attacked and despoiled. Among the slain was the seer of Pethor, Balaam the son of Beor.
The Moabites must have hailed the Israelites as saviours. They had delivered them from their two assailants, the Amorites on the north, the Midianites on the east. But the Midianite power was broken only for a time. We hear at a subsequent date of the Edomite king Hadad "who smote Midian in the field of Moab," and a time came when Midianite shêkhs overran Gilead, and penetrated into the valleys and villages of Manasseh on the western side of the Jordan. After their defeat by Gideon, however, we hear of them no more. They passed out of the Israelitish horizon; henceforth their raiding bands never approached the frontiers of Israel. The land of Midian alone is mentioned as adjoining Edom; the Midianites who had traversed the desert and carried terror to the inhabitants of Canaan become merely a name.
Midian was originally governed by high-priests. This was the case among other Semitic peoples as well. In Assyria the kings were preceded by the high-priests of Assur, and recently-discovered inscriptions show that in southern Arabia, in the land of Sheba, the high-priest came before the king. Jethro, "the priest of Midian," represented a peculiarly Arabian institution.
The name of "Arab" was applied to certain tribes only of northern Arabia. We hear of them in the Old Testament as well as in the Assyrian inscriptions. In the Old Testament the name seems to include the Ishmaelite clans to the east of Edom. Their "kings," it is said, brought tribute to Solomon; a colony of them was established at Gur-Baal in the south of Judah. We learn from the Assyrian texts that they could be governed by queens; two of their queens indeed are mentioned by name.
It was also a "queen of the south," it will be remembered, who came to hear the wisdom of Solomon. Sheba, the Saba of classical antiquity, was an important kingdom of south-western Arabia, which had grown wealthy through its trade in spicery. From time immemorial Egypt had imported frankincense from the southern coasts of the Arabian peninsula, and the precious spices had been carried by merchants to the far north. The caravan-road of trade ran northward to Midian and Edom, touching on the one side on the frontier of Egypt, on the other on that of Palestine. The road and the country through which it passed were in the hands of the south Arabian kings. Their inscriptions have been discovered at Teima, the Tema of the Old Testament, not far inland from El-Wej, and in the days of Tiglath-pileser the kings of Saba claimed rule as far as the Euphrates. It was no strange thing, therefore, for a queen of Sheba to have heard of the power of Solomon, or to have sought alliance with so wealthy and luxurious a neighbour. His province of Edom adjoined her own possessions; his ports on the Gulf of Aqaba were open to her merchants, and the frankincense which grew in her dominions was needed for the temple at Jerusalem.
