Father-in-law of Moses (Judg. 4: 11, so NRSV and NJB). But Num. 10: 29, in the J source speaks of Hobab the son of Reuel, Moses' father-in-law, and it is not clear whether this means Hobab or Reuel as the father-in-law. If the latter, then Hobab is Moses' brother-in-law, which is the REB translation at Judg. 4: 11. Moses' father-in-law is also sometimes called Jethro (Exod. 3: 1).
