Commento su Genesi 26:19

ויחפרו, they dug even deeper than initially in order to supply sufficient water for the livestock.

וימצאו שם באר מים חיים, “they found a well of spring water in that region.” The reason the Torah stresses the origin of this water is that the shepherds of the region had accused Yitzchok’s shepherds of diminishing their own water supply by letting their sheep drink from the water of the נחל, the local stream. The water found by Yitzchok’s shepherds did not originate in that stream, but represented a new and additional water supply. Yitzchok’s herds and flocks did not need to use the locally available sources of water.

He named the well Eisek [Quarrel]. This well foreshadowed the First Holy Temple, in the time of which the kings of Judah and Israel, Israel’s “shepherds,” quarreled over the kingship and as an offshoot of their quarrel the shepherds of the nations also joined the fray.

וימצאו שם באר מים חיים, after they kept digging, they found this additional well beneath the old well. This is why the Torah did not write that they found מים, i.e. simply water, but באר, that they found a new source of water.

Sitnah [Obstruction] (or “Hatred”). This foreshadowed the Second Holy Temple, in the time of which baseless hatred became rampant. Eisek implies strife over a specific issue, whereas sitnah implies hatred for no reason.

Rechovos [Wide Spaces]. This foreshadowed the Third Holy Temple, in the time of which the land will seem spacious because peace will reign among Israel.
