English: “He sent Yehudah ahead of him to Yosef, to show the way (lehorot) before him to Goshen” — “lehorot” means to teach. Yaakov sent Yehudah to prepare a house of study for him in Goshen, so that they would study Torah there.
On the daf / in context: The midrash reads the verb not merely as “to direct the way” but as “to instruct / to establish teaching,” making Yehudah’s mission the founding of a beit midrash before the family’s arrival.
Type of Learning
Derash on the verse (midrash) — not a formal named middah of the 13. A single verb is expanded from geographic guidance to the establishment of Torah study.
What Is Learned
Yaakov’s first priority upon entering Egypt was the establishment of a house of Torah study; he sent Yehudah ahead for that purpose.
