Moses tells us nothing of what he may have learned from his father-in-law, but he must have found in him a man conversant with the traditions of the family of Abraham; nor is there any improbability in the supposition that, as hereditary priest, Reuel may have possessed written documents concerning their common ancestors.

Zipporah his daughter - Abul Farajius calls her "Saphura the black, daughter of Rewel the Midianite, the son of Dedan, the son of Abraham by his wife Keturah." The Targum calls her the granddaughter of Reuel. It appears that Moses obtained Zipporah something in the same way that Jacob obtained Rachel; namely, for the performance of certain Services, probably keeping of sheep: see Exodus 3:1.

And Moses was content to dwell with the man,.... After he had been called and brought into the house, and had had some refreshment, and after some conversation had passed between them, and perhaps after some days' stay in Reuel's house; Reuel having observed his disposition and behaviour, and being delighted therewith, proposed to him to take up his residence with him, with which motion Moses was well pleased, and accepted of it:
and he gave Moses Zipporah his daughter; to be his wife. It is not to be supposed that this was done directly; though both Philo (u) and Josephus (w) intimate as if it was done at first meeting together; but it is not likely that Reuel would dispose of his daughter so suddenly to a stranger, though he might at once entertain an high opinion of him; nor would Moses marry a woman directly he had so slender an acquaintance with, so little knowledge of her disposition, endowments of mind and religion. The Targum of Jonathan says it was at the end of ten years; and indeed forty years after this a son of his seems to have been young, having not till then been circumcised, Exodus 4:22. The author of the Life of Moses says (x), that he was seventy seven years of age when he married Zipporah, which was but three years before he returned to Egypt. This circumstance of Moses's marrying Reuel's daughter is confirmed by Artapanus (y) an Heathen historian; and also by Demetrius (z), and expressly calls her Sapphora, who he says was a daughter of Jother or Jethro; and likewise by Ezekiel the tragedian (a).

Moses' Life in Midian. - As Reguel gave a hospitable welcome to Moses, in consequence of his daughters' report of the assistance that he had given them in watering their sheep; it pleased Moses (ויּואל) to dwell with him. The primary meaning of הואיל is voluit (vid., Ges. thes.). קראן for קראנה: like שׁמען in Genesis 4:23. - Although Moses received Reguel's daughter Zipporah as his wife, probably after a lengthened stay, his life in Midian was still a banishment and a school of bitter humiliation. He gave expression to this feeling at the birth of his first son in the name which he gave it, viz., Gershom (גּרשׁם, i.e., banishment, from גּרשׁ to drive or thrust away); "for," he said, interpreting the name according to the sound, "I have been a stranger (גּר) in a strange land." In a strange land he was obliged to live, far away from his brethren in Egypt, and far from his fathers' land of promise; and in this strange land the longing for home seems to have been still further increased by his wife Zipporah, who, to judge from Exodus 4:24., neither understood nor cared for the feelings of his heart. By this he was urged on to perfect and unconditional submission to the will of his God. To this feeling of submission and confidence he gave expression at the birth of his second son, by calling him Eliezer (אליעזר God is help); for he said, "The God of my father (Abraham or the three patriarchs, cf. Exodus 3:6) is my help, and has delivered me from the sword of Pharaoh" (Exodus 18:4). The birth of this son is not mentioned in the Hebrew text, but his name is given in Exodus 18:4, with this explanation.
(Note: In the Vulgate the account of his birth and name is interpolated here, and so also in some of the later codices of the lxx. But in the oldest and best of the Greek codices it is wanting here, so that there is no ground for the supposition that it has fallen out of the Hebrew text.)
In the names of his two sons, Moses expressed all that had affected his mind in the land of Midian. The pride and self-will with which he had offered himself in Egypt as the deliverer and judge of his oppressed brethren, had been broken down by the feeling of exile. This feeling, however, had not passed into despair, but had been purified and raised into firm confidence in the God of his fathers, who had shown himself as his helper by delivering him from the sword of Pharaoh. In this state of mind, not only did "his attachment to his people, and his longing to rejoin them, instead of cooling, grow stronger and stronger" (Kurtz), but the hope of the fulfilment of the promise given to the fathers was revived within him, and ripened into the firm confidence of faith.
