ESODO 3:1

OR Mosè pasturava la greggia di Ietro, sacerdote di Madian, suo suocero; e guidando la greggia dietro al deserto, pervenne alla montagna di Dio, ad 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.
