18:5 And Jethro, Moses' father in law, came with his sons and his wife unto Moses into the wilderness, where he encamped at the {b} mount of God:
(b) Horeb is called the mount of God, because God did many miracles there. So Peter calls the mount where Christ was transfigured, the holy mount: for by Christ's presence it was holy for a time, 2Pe 1:18.
18:1-6 Jethro came to rejoice with Moses in the happiness of Israel, and to bring his wife and children to him. Moses must have his family with him, that while he ruled the church of God, he might set a good example in family government, 1Ti 3:5.
