“And Isaac digged again the wells of water, which they had digged in the days of Abraham.”
– Genesis 26:18, JPS 1917 Tanach
Meor Eynayim explains, that these wells are symbolic of G-d’s wisdom that flowed during the lifetime of Abraham; yet, after his death, his wells were stopped up by the Philistines, representative of the powers of darkness and ignorance, inasmuch that they also impeded the spread of this wisdom (Meor Einayim, Toldos 19; sefaria.org). Symbolically, when Isaac redug the wells of his father, Abraham, he also reopened the flow of divine wisdom into the world.
The wellsprings of wisdom, must be dug within ourselves, until we reach the place where the source of the wisdom flows. This is the essence of the teaching from Meor Einayim. In reference to the verse, “they have forsaken me, the source of living waters (Jeremiah 2:13), he explains that “Blessed G-d is the source from whom comes the flow of life-force to all living things in all manners” (Meor Einayim, Toldos 18; sefaria.org).
Thus, the source of life continually flows from G-d; yet, as the result of sin, we cause a blockage of that source, and are likened to “broken cisterns.” Consequently, we are unable to connect to our “upper root,” the source above us that nourishes our soul. Additionally, our own ignorance compels us to search elsewhere in this world for the truth; yet, here is much spiritual malaise as the result of sin in this world. Our own path should be to turn from the the darkness, towards the light, so that our souls may be renewed with G-d’s wisdom.
Tradition teaches that preceding the time of Moshiach (Messiah), there will be a decline in spiritual understanding, as a result of sinking to “the fiftieth level of impurity.” However, at the beginning of his reign, “it shall come to pass in that day, that living waters shall go out from Jerusalem” (Zechariah 14:8). Pirkei deRabbi Eliezer, explains that in the future, within Jerusalem, a newfound well that will arise of its own accord, will water all of the surroundings. “The earth shall be full of the knowledge of the L-RD, as the waters cover the sea” (Isaiah 11:9, JPS 1917 Tanach).
