John Gill's Bible Commentary Ver. 9. And Moses sware on that day, saying , etc.] Or declared the oath of the Lord, for it was the Lord that sware to what follows; (see Deuteronomy 1:34-36); surely the land whereon thy feet have trodden shall be thine inheritance, and thy children’s for ever : not the whole land of Canaan, nor all the parts of it Caleb travelled through, but particularly Hebron; which though not expressly mentioned in the aforesaid oath, yet was understood and known to be the meaning of it, and which Joshua by the following grant owned, and it is elsewhere expressly affirmed, ( Judges 1:20); and it is remarked, that it is not said “they”, but “he” came to Hebron, ( Numbers 13:22); that is Caleb, so that it was literally true that his feet had trodden there: now the reason of this oath, and the inheritance assured by it to Caleb, was, because thou hast wholly followed the Lord thy God ; in all his ways, and with full purpose of heart, and particularly had acted the upright and faithful part in the report he made of the good land; (see Gill on “ Numbers 14:24”).
Matthew Henry Commentary
Verses 6-15 - Caleb's request is, "Give me this mountain," or Hebron, because it wa formerly in God's promise to him, and he would let Israel knows ho much he valued the promise. Those who live by faith value that which is given by God's promise, far above what is given by his providence only It was now in the Anakims' possession, and Caleb would let Israel know how little he feared the enemy, and that he would encourage them to push on their conquests. Caleb answered to his name, which signifie "all heart." Hebron was settled on Caleb and his heirs, because he wholly followed the Lord God of Israel. Happy are we if we follow him Singular piety shall be crowned with singular favour _________________________________________________
