וַיָּ֨שָׁב יִצְחָ֜ק וַיַּחְפֹּ֣ר ׀ אֶת־בְּאֵרֹ֣ת הַמַּ֗יִם אֲשֶׁ֤ר חָֽפְרוּ֙ בִּימֵי֙ אַבְרָהָ֣ם אָבִ֔יו וַיְסַתְּמ֣וּם פְּלִשְׁתִּ֔ים אַחֲרֵ֖י מ֣וֹת אַבְרָהָ֑ם וַיִּקְרָ֤א לָהֶן֙ שֵׁמ֔וֹת כַּשֵּׁמֹ֕ת אֲשֶׁר־קָרָ֥א לָהֶ֖ן אָבִֽיו׃
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.
Redeeming Relevance; Genesis
Yitzchak’s attitude toward the world is also highlighted by comparing his manner of dealing with human conflict with that of Avraham and Yaakov. In the parallel stories of Avraham and Yitzchak’s conflict with the Philistines over the control of wells dug by their respective retinues, Avraham does not shy away from rebuking Avimelech over the matter (Bereshit 21:25). In contrast, it seems fair to infer that Yitzchak relies on the hope that eventually God will step in, and he therefore directs his followers to keep digging wells until eventually the local inhabitants leave them alone (Bereshit 26:18–22). While Yitzchak does question Avimelech about his people’s attitude toward him, the question is more of a clarification than a rebuke (Bereshit 26:27). Indeed, not only does Yitzchak not mention the conflict over the wells, he does not even mention the fact that Avimelech has previously expelled him from his territory. It appears that Yitzchak is not interested in bringing up such matters and views redress of such issues as unnecessary.

ועמק השדים בארות בארות חמר, the vowel pattern of the construct mode of the word בארות in our verse is different from the ordinary plural mode of the same word in Genesis 26,18 where it also appears in the construct mode, i.e. בארות המים, “the wells of water.”
Ramban
IN THE VALLEY OF GERAR, far away from the city. And [Isaac] digged again the wells of water, which they had digged in the days of Abraham his father, and which the Philistines had stopped up before Isaac left Gerar, he once again dug. Thus the words of Rashi.
It would appear from Rashi’s words, then, that the wells mentioned here [in Verse 18] are the same as those mentioned [above in Verse 15]: For all the wells which his father’s servants had digged in the days of Abraham his father the Philistines had stopped them, and filled them with earth. But this is not so, for how would the Philistines give him permission when they had said, “These wells are a source of danger to us because of invaders.”170Quoted in Rashi, Verse 15 here. Rather, the wells [mentioned in Verse 18] are different ones in another location since the valley of Gerar is the name of a place, or perhaps the valley extended from Gerar to another land, and when the Philistines, namely, the lords of Gerar — the principality of the king — became jealous of Isaac, they stopped the wells which were his by inheritance from his father in the boundary of the city of Gerar. The king then sent him away from his throne-city, and he went to another city. Possibly, this new place was not part of his kingdom even though it was in the land of the Philistines. There were other wells there which Abraham had dug when he lived there for many days171Above, 21:34. but which the Philistines stopped upon his death since Isaac did not dwell there. They did not do this out of hatred. But in the days of Abraham, [even after he had moved from there], they did not want to stop them out of respect to him, saying, “Perhaps he will return to dwell there.” This was why Isaac returned and dug them in the valley. But the herdsmen of the valley quarrelled with him saying, The water is ours,172Verse 20 here. meaning, “The well is in the valley, and the waters ooze forth from that valley while those in the valley are diminished. Hence they are ours.” It is for this reason that Scripture mentions, And they found there a well of living water,173Verse 19 here. stating that it was a source gushing forth living water which did not come from the valley as those who quarrelled with Isaac had previously claimed.
