John Wesley on Numbers 10:29

Raguel - Called also Reuel, Exo 2:18, who seems to be the same with Jethro; it being usual in scripture for one person to have two or three names. And therefore this Hobab is not Jethro, but his son, which may seem more probable, because Jethro was old and unfit to travel, and desirous, as may well be thought, to die in his own country, whither he returned, Exo 18:27, but Hobab was young and fitter for these journeys, and therefore entreated by Moses to stay and bear them company.
