At muling hinukay ni Isaac ang mga balon ng tubig na hinukay noong panahon ni Abraham na kanyang ama, na tinabunan ng mga Filisteo pagkamatay ni Abraham; at tinawag niya ang mga ito sa mga pangalang gaya ng mga pangalang itinawag sa mga ito ng kanyang ama.
Shenei Luchot HaBerit
This explains the whole matter of Isaac digging up the wells which Abraham had dug and which the Philistines had stopped up again after Abraham had left the district. The whole episode is puzzling, as the Torah had previously reported Isaac as experiencing a supernatural amount of blessing (26,12). Why should this be followed by hostility on the part of his neighbors? Another difficulty is why the Torah supplies a reason for the names Isaac gave the wells only for the first and third well, whereas the Torah does not mention why the second well was named Sitnah, harassment (26,21). Another difficulty is the word עתה in 26,22. It would have sufficed for Isaac to name that well רחובות by saying כי הרחיב ה' לנו ופרינו בארץ.
