They went up into the Negev and he came to Chevron, and there were Achiman, Sheshai, and Talmai, the children of the Anak. And Chevron was built seven years before Tzoan of Egypt.
Torah Temimah on ויבא עד חברון: Sotah 34b — Calev separated from the spies’ counsel and prostrated on the graves of the Patriarchs.
Sefaria — Sotah 34b · E-Daf — Sotah 34b
English: “They went up in the Negev and he came to Chevron” — it should have said “they came”? Rava said: This teaches that Calev separated from the spies’ counsel and went and prostrated on the graves of the Patriarchs. He said to them: My fathers! Seek mercy for me that I be saved from the spies’ counsel.
Singular vs plural — the singular “he came” isolates Calev’s path.
Calev alone went to Chevron to pray at the Patriarchs’ graves for strength against the spies.
