Josh 14:13

“And so, let us see who it is who first receives the inheritance from Jesus [Joshua]: "Caleb," it says, "the son of Jephunneh." For he requests first with certain fixed reasons and words that are described, words that are also able to instruct us for salvation.First of all, Caleb is interpreted "as a heart." Who, therefore, is "as a heart" if not the one who in all things has devoted effort to discernment, who is not said to be just any member of the body of the church but that one that is the more admirable in us, the heart? That is, he is the one who bears all things with reason and prudence and so arranges all things as if being none other than the heart. But also Jephunneh, his father, is interpreted "conversion." Therefore, this Caleb is the son of conversion. Why, unless he were converted to God, could Jephunneh produce from himself such fruit that he begat a heart as a son? Thus Caleb is everyone who is devoted to divine understandings and who conducts all things wisely and reasonably.”

“Thus, therefore, even now this very wise Caleb stands before Jesus [Joshua] and promises to be mighty for war and ready for battle. On that account he earnestly demands to be granted the faculty of disputation that he may contend with the dialecticians of the age who hold deceits for truth, to refute them and to subdue and to overthrow all the things that they have established with their false assertions. Moreover, finally, seeing his ardor, "Jesus [Joshua] blesses him," it says; doubtless because he demands and dares such things. But you too, if you are willing to give attention to studies and wisely to contemplate the law of God and to be made a "heart" in the law of God, you can overthrow these great and fortified towns, that is, the assertions of falsehood. Then you also may deserve to be blessed by Jesus and to receive Hebron from him.”

“Then Joshua blessed Caleb, i.e., implored the blessing of God upon his undertaking, and gave him Hebron for an inheritance. Hebron is mentioned as the chief city, to which the surrounding country belonged; for Caleb had asked for the mountains (Jos 14:9), i.e., the mountainous country with and around Hebron, which included, for example, the fortified town of Debir also (Jos 15:15).”
