Exodus 3:1 - Coke's Commentary on the Holy Bible

Jethro his father-in-law, &c.— See note on ch. Exodus 2:18. What we render, the back-side of the desert, the Vulgate has the inner parts of the desert; where, probably, there was the best pasture: and so the Chaldee renders it, the best pastures of the desert. Horeb might be called the mountain of GOD, either from God's appearance there now, or because of his giving the law from it afterwards. Some suppose that it is so called, from its great height; as, Psalms 36:6 the great mountains are called in the original, the mountains of God. Josephus has preserved a tradition, that it was given out in the times before Moses, that a Divinity had often appeared on this mount. Horeb and Sinai were two tops of the same mountain; which accounts for their being so frequently named the one for the other; as, Acts 7:30. St. Stephen calls that Sinai, which Moses here calls Horeb. Some suppose, that Moses, during his forty years' continuance with Jethro, wrote the book of Genesis, as well as that of Job.
