Komentarz do Rodzaju 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.
