E'sek (Hebrew id. עֵשֶׂק, quarrel; Sept. and Vulg. translate Α᾿δικία, calumnia, as if reading עשֶׁק), a well (בּאֵר) containing a spring of water, which the herdsmen of Isaac dug in the valley of Gerar, and which received its name because the herdmen of Gerar quarreled הַתעִשׁקוּ, wrangled, Sept. ἠδίκησαν, Vulg. evasively, A.V. "strove;" but different from the וִיָּרַיבוּ of the preceding clause, ἐμαχήσαντο, jurgiun fuit, "strove") with him for the possession of it (Ge 26:20). Isaac seems to have therefore relinquished it. It appears not to have been one of those which Abraham had previously dug (verse 18; the contest there was a question of title, here of possession). There are still several wells in this vicinity.
