Komentaryo sa Mga Bilang 32:12: Rashi, Rabbeinu Bahya, Chizkuni & Siftei Chakhamim

הקנזי [CALEB THE SON OF JEPHUNNEH] THE KENEZITE — He (Caleb) was the stepson of Kenaz (and therefore he is termed here the Kenezite), and Caleb's mother bore Othniel to him (to Kenaz) (and for this reason Othniel, the son of Kenaz is described in Joshua 15:17 as Caleb’s brother) (Sotah 11b).

בלתי כלב בן יפונה הקנזי, “except for Calev, son of Yephuneh the Kenizite.” Our sages (Sotah 11) derive from here that Calev was a stepson of Kenaz for whom the mother of Calev had born Othniel.

בלתי כלב בן יפונה, ”except for Calev, son of Y’funeh.” If you were to ask how come that also Yair, son of Menashe entered the Holy Land (crossed the Jordan) and was killed during the siege on Ai, together with 35 comrades in arms (Talmud tractate Sanhedrin, folio 44) (according to Joshua 7,8) we have to answer that the decree issued after the Sin of the Spies concerning who would not be allowed to enter the Holy Land did not apply to people under the age of twenty at the time it was decreed, nor did it apply to people over the age of fifty, as neither category would have been drafted into military service, so that the spies’ refusal to undertake a campaign against the Canaanites would not have affected them personally.
