ליטעראַטור פֿון בית שני אויף בראשית 26:32

This is why the diggers of this well say that they found no water in it (Gen. 26:32), inasmuch as the ends pursued in the different branches of knowledge prove to be not only hard to reach, but absolutely beyond finding.

[38] To say that she “stood still from bearing” (Gen. 29:35) differs not at all from saying that the servants of Isaac found no water in the fourth well (Gen. 26:32), since what is brought out by each of the figures is that all things are athirst for God, through Whom the birth of things, and their food when born, is watered into fruitfulness.

(α) 74–93. Abraham’s planting (Gen. 21:33). The tree the “hide” of 10,000 cubits; the place the well, which is without water (Gen. 26:32 LXX), and so symbolic of the fruitless search for knowledge, and of the discovery of our own ignorance; the fruit the invocation of the Name “Eternal God,” which connotes “Benefactor,” whereas “Lord” connotes Master.”
