Numbers 32:12

Save Caleb the son of Jephunneh the Kenezite, and Joshua the
son of Nun
See ( Numbers 14:30 ) , whether Caleb or Jephunneh is called the Kenezite is not so easy to determine; the latter rather seems to be most correct, for that Caleb should be called so from Kenaz the father of Othniel, who is said to be Caleb's brother seems not to be agreeable; since it is not likely that they were his own brothers, or Caleb would not have given his daughter to him; besides Jephunneh and not Kenaz is always said to be the father of Caleb, unless his father can be thought to have two names; it is most likely that Jephunneh, and so Caleb, might be called the Kenezite, from an ancestor of theirs of that name: Jarchi says, Caleb was the son-in-law of Kenaz, and Caleb's mother bore unto him Othniel:

for they have wholly followed the Lord;
here what was said of Caleb, ( Numbers 14:24 ) is said both of him and Joshua; (See Gill on Numbers 14:24).
