Commentary for Genesis 46:28

להורת לפניו TO DIRECT HIM — Render this as the Targum does: to prepare a place for him and to show him how he should settle in it.

להורות לפניו גושנה, in order to make a clearing where suitable accommodation could be built for Yaakov and the family.

ואת יהודה, Yaakov sent him ahead to Joseph in order for him to be given details about Goshen, the part of the country Joseph had said his brothers would be settled in (45,10) Alternatively, the meaning of our verse may be that the word להורות, refers to Yehudah providing information to Yaakov, to make sure the family would proceed on the best route and the best location in Goshen.

To prepare a house of study... I.e., since it is written להורת without a second vav, it contains the letters [of the word] תורה.

להורות לפניו: damit Josef, ehe er hinkam, ihm die Anweisung gebe, nach Goschen zu ziehen. Es solle nicht scheinen, als ob er eigenmächtig mit seiner Familie dort einzöge, obwohl er "Väter des Fürsten", oder vielmehr, weil er dieses war. Jakob kannte die Welt und wusste, wie jeder ihn nach sich beurteilen und ihm eine eigenmächtige Willkür andichten könnte, die er sich in solcher Stellung selbst erlauben würde.

ואת יהודה שלח לפניו אל יוסף, “and he (Yaakov) had sent Yehudah ahead to Joseph;” so that he would be informed about which route to travel to the province of Goshen and thus to avoid entering Egypt proper. Joseph had already told him that he would live there in order to be close to Joseph (Genesis 45,6).

They then came to the land of Goshen. Yoseif and Yehudah went to Goshen to prepare a place for Yaakov and it was from there that Yoseif went to greet him.

לפניו BEFORE HIM — means before he should arrive there. A Midrashic comment is: להורת לפניו (in the sense of, “that there might be teaching before him”) — to establish for him a House of Study from which Teaching (הוראה or תורה) might go forth (Genesis Rabbah 95:3).
