We see, says the Satmar Rav, that wherever the essence of something is found, it is as if the entire thing is there. Effectively, then, he never left the Holy Land. You, Yosef are the one who is causing insult to the king. Just as a king's subjects reflect the king's values, so students are a reflection of their teachers, and children, of their parents. In fact, Chazal say that the 400 years of the exile began with the birth of Yitzchak, and he never left Eretz Yisrael.
Exile is in the eye of the beholder.
For Yitzchak, living in an Eretz Yisrael that was ruled by a non-Jewish king was exile. However, Yaakov's favoritism towards Yosef led the Jews to go to Egypt, and there they fell in stature until only actual enslavement could be considered exile. And Yaakov traveled, and he came to Be'er Sheva, and he brought sacrifices to the G-d of his father Yitzchak. Yitzchak, for example, went to Be'er Sheva after he was chased out of Gerar. Yaakov, as our verse says, stopped in Be'er Sheva on his way to Egypt.
