וַיְדַבְּרוּ אֵלָיו אֵת כָּל דִּבְרֵי יוֹסֵף אֲשֶׁר דִּבֶּר אֲלֵהֶם וַיַּרְא אֶת הָעֲגָלוֹת אֲשֶׁר שָׁלַח יוֹסֵף לָשֵׂאת אֹתוֹ וַתְּחִי רוּחַ יַעֲקֹב אֲבִיהֶם - And they told him all of Joseph's words that he had said to them, and he saw the wagons that Joseph had sent to carry him, and the spirit of their father Jacob was revived. (Br 45:27)
Rashi comments that יוֹסֵף sent agalos (wagons) and upon seeing the wagons, יַעֲקֹב was reminded of eglah arufah, the last Torah topic they learned together.
Whereas Rashi focuses on the first words, וַיַּרְא אֶת הָעֲגָלוֹת, the Kli Yakar emphasizes - that אֲשֶׁר שָׁלַח יוֹסֵף – that יוֹסֵף sent) as the key component that brought יַעֲקֹב back to life.
What can we learn from יוֹסֵף 's action of escorting (liviya) ones guest(s)?
