Either 1. Strictly, and then he is the same who elsewhere is called Iethro, Exod. 3. 1. and 18. oft-times, and, as some think, Hobab, Iudg. 4. 11. Or 2. largely, i. e. their grandfather, for such are oft called fathers, as Gen. 31. 43. 2 King. 14. 3. &c. and 16. 2. and 18. 3. so he was the father of Iethro, or Hobab, Numb. 10. 29.
