“Ganyan din ang ginawa ng inyong mga ama nang suguin ko sila mula sa Kades-barnea upang tingnan ang lupain.”
Rashi
מקדש ברנע FROM KADESH-BARNEA — this was its name. There were two places called Kadesh (therefore this one is distinguished from the other by being called Kadesh-Barnea).
Siftei Chakhamim
There were two places named Kadeish. Meaning that when it writes Kadeish Barnei’a you should not say that it was named Kadeish and its ruler was called Barnei’a, as with Elonei Mamre (Bereishis 13:18) where the owner of the plain was called Mamre. Therefore, Rashi explains, “This was its name” and Kadeish Barnei’a was the name of that place. But since elsewhere (24:14, 33:37) Kadeish is mentioned alone, Rashi therefore explains that there were two places named Kadeish.
