EXODE 3:1

Moïse faisait paître le troupeau de Jéthro, son beau-père, sacrificateur de Madian; et il mena le troupeau derrière le désert, et vint à la montagne de Dieu, à Horeb.

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.
