John Chrysostom
I am obligated to carry out the commands of my Father. Once I have accomplished His purpose, I will come back.
For my father made me swear to him, saying: Behold I die; thou shalt bury me in my sepulchre which I have digged for myself in the land of Chanaan. So I will go up and bury my father, and return.
אָבִ֞י הִשְׁבִּיעַ֣נִי לֵאמֹ֗ר הִנֵּ֣ה אָנֹכִי֮ מֵת֒ בְּקִבְרִ֗י אֲשֶׁ֨ר כָּרִ֤יתִי לִי֙ בְּאֶ֣רֶץ כְּנַ֔עַן שָׁ֖מָּה תִּקְבְּרֵ֑נִי וְעַתָּ֗ה אֶֽעֱלֶה־נָּ֛א וְאֶקְבְּרָ֥ה אֶת־אָבִ֖י וְאָשֽׁוּבָה׃

Joseph instructed Pharaoh's nobles to speak on his behalf to Pharaoh. After the period of mourning for Jacob ended, Joseph felt it was essential to grieve for his father until he could bury him in Canaan. His appearance was marked by disheveled hair, sorrowful attire, and a lack of cleanliness, which made him think it inappropriate to approach Pharaoh in such a condition. Therefore, he chose to communicate through intermediaries for this request. Pharaoh, in turn, relayed his approval to Joseph through others, allowing the transport of Jacob's body to Canaan for burial in the family tomb where Jacob had previously prepared a resting place for himself.
