Kabbalah su II Samuele 23:20

Come and behold, it is written "And Benaiah the son of Jehoida, the son of a valiant (lit. 'living') man" (II Shmuel 23:20). This means that he was righteous and illuminated his generation as the living one above illuminates the world. Thus, the well constantly looks to the living one in order to be illuminated. "And Isaac dwelt by Be'er Lachai Ro'i. "It is written, "When he took Rivkah," FOR and as he united with her, the joining of darkness and night, as it is written, "his left hand is under my head" (Shir Hashirim 2:6) And Come and behold, Isaac was in Kiryat Arba after Abraham died. What about the verse that reads, "And Isaac dwelt by Be'er Lachai Ro'i?" That with which he joined and was united in that well, to stir up love, as we said.

He began with the verse, "Benaiah the son of Jehoiada" (II Samuel 23:20). This verse has been explained, and explained well! But it came to show us the sublime secrets of the Torah. "Benaiah the son of Jehoiada" has been mentioned [as referring to] the secret of wisdom. It is a clue to something deep and concealed, and the name caused it. "a brave soldier who performed great deeds" applies to the Righteous, with life of the worlds. "Mighty of deeds" means that he is the Master of all actions and of all the hosts on high, because they all come from him. He [God] is "haShem Tzeva'ot" [because he is] the sign throughout His hosts and is distinguished as he stands high above them all.
