A well-known tradition raises this very question: Where did Isaac go? Genesis Rabbah 56:11 suggests that Abraham sent Isaac to Shem to study Torah. Similarly, the Targum Jonathan on Genesis 22:19 states: “The angels on high took Isaac and brought him to the school of Shem the Great, where he remained for three years.”
The biblical text itself is silent about Isaac’s movements at that moment, leaving room for interpretation. However, his sudden absence could also be seen symbolically. Since Isaac in the Akedah foreshadowed the Messiah’s death and resurrection, his disappearance after the event invites reflection: just as the Messiah rises and goes to prepare a place for His bride, Isaac disappears from the scene, and the narrative immediately shifts to the genealogy of Rebekkah, the bride who would soon be given to him. This pattern reinforces the typology: sacrifice → absence → bride prepared
Another interesting point is that after the Akeda, there are no further recorded conversations between Abraham and Isaac. However, the mention of Rebekka’s genealogy and Abraham’s sending his servant Eliezar to fetch a bride points to another pattern. We see the earthly mirroring of the divine Father as He prepares the Bride for His Divine Son.
