Revel their father] He was (as some thinke) their grandfather, and (in Scripture) the Ancients (in a direct line) are called fathers, and their nephewes children, Genesis 31:43. and so one man may have many fathers, Acts 24:14. But here it is more probable, that one father had many names, and that this Priest of Midian, was called Revel in this place, and Jethro, 3. 1. &Chap. 18. often, and Hobab, Judg. 4. 11. whose father was Raguel the Midianite.
