Exodus 3:1

Now Moses kept the flock of Jethro his father in law, the priest of Midian: and he led the flock to the backside of the desert, and came to the mountain of God, [even] to Horeb.

Ver. 1. To the backside of the desert,] Here it was that Moses wrote the book of Genesis, and that of Job too, as some conceive, a for the comfort of his poor oppressed countrymen in Egypt, that they might lean upon, and live by faith in, the promises made to the fathers.
