Where was Isaac during all this? The Torah says he was "coming from Beer-lahai-roi." Targum Pseudo-Jonathan on Genesis 24:62 tells us something far more specific. He was coming from the beit midrash — the house of study — of Shem Rabba, Shem the Great, son of Noah.
Pause on that image. While Eliezer was riding north with ten camels, Isaac was sitting in a classroom. And not just any classroom. Shem was the teacher the Rabbis imagined as the first yeshiva head of the covenantal lineage — the righteous son of Noah who carried the knowledge of God forward through the generations before Abraham.
The Targum names the specific well where Isaac had been formed: the fountain "where had been revealed to him the Living and Eternal One, who seeth and is not seen." This is Beer-lahai-roi, the well where Hagar had also met the angel (Genesis 16:13-14). Isaac has been living near the place where the God who sees meets those who cannot see Him back.
The symmetry is gorgeous. The father's servant brings a bride up the road from the north. The son comes up the road from the south, from the well of God's presence. They will meet in the middle, and a new generation will begin at the exact point where study and providence collide.
The Maggid's lesson is simple. If you want a holy marriage, spend the waiting season in the house of study. Isaac was not idle. He was not anxious. He was learning Torah at Shem's feet, while somewhere to the north, the road was leaping toward him.
