Josh 14:14

“But Hebron means "union" or "marriage." Perhaps this can be expressed by Hebron because the double cave purchased by the patriarch Abraham is there, and the remains of the fathers and their wives lie there: Abraham with Sarah, Isaac with Rebecca, and Jacob with Leah. Thus Caleb deserved to receive the remains of the fathers for an inheritance, because no doubt through the wisdom that was in him and by which he flourished both under Moses and under Jesus [Joshua], he had understood the nature of the union itself. He had perceived the reason why only Sarah lay there with Abraham and that neither Hagar nor Keturah deserved to be joined with him; or the reason why only Leah seems to lie with Jacob, and that neither Rachel, who had been loved more, nor any of the concubines was united with him in the tomb. Therefore, prudent and wise Caleb takes the inheritance with the monuments of the fathers. Jesus [Joshua] granted to him Hebron, a mother city of the Anakim nation, and it becomes "a share" for him "up to the present day."”

“This inheritance, the historian adds, was awarded to Caleb because he had followed the God of Israel with such fidelity. - In Jos 14:15 there follows another notice of the earlier name of Hebron (see at Gen 23:2). The expression לפנים (before), like the words "to this day," applies to the time when the book was composed, at which time the name Kirjath-arba had long since fallen into disuse; so that it by no means follows that the name Hebron was not so old as the name Kirjath-arba, which was given to Hebron for the first time when it was taken by Arba, "the great man among the Anakites," i.e., the strongest and most renowned of the Anakites (vid., Jos 15:13). The remark, "and the land had rest from war," is repeated again at the close of this account from Jos 11:23, to show that although there were Anakites still dwelling in Hebron whom Caleb hoped to exterminate, the work of distributing the land by lot was not delayed in consequence, but was carried out in perfect peace.”
