וְאֶת־יְהוּדָ֞ה שָׁלַ֤ח לְפָנָיו֙ אֶל־יוֹסֵ֔ף לְהוֹרֹ֥ת לְפָנָ֖יו גֹּ֑שְׁנָה וַיָּבֹ֖אוּ אַ֥רְצָה גֹּֽשֶׁן׃
И послал Иудею пред ним в Иосифа, чтобы показать путь перед ним в Гесем; и пришли они в землю Гесем.
Shenei Luchot HaBerit
ואת יהודה שלח לפניו . Jacob's purpose was to establish a Torah academy in advance of the family's arrival in Goshen. Spiritual needs have to be attended to first. When building a home, one must first plan the study in which one learns Torah and says one's prayers. This room should also serve as a place for quiet contemplation and as a meeting place for scholars. Only after having attended to this does one plan the remainder of the house.
