A good guest is called “the good inclination,” which comes at thirteen years. “Great is having guests,” since the body does not let it in.
“I was a stranger in a foreign land,” which means a foreign desire, the desire of a foreigner and not the desire of Israel.
Ysrael [Israel] is called Yashar-El [straight to the Creator]. Conversely, a foreign desire is a desire for a foreign God, as our sages said about the verse, “There shall be no strange God within you,” and they explained, “Who is a strange God in man’s body? It is the evil inclination” (Shabbat 105b).
Before a person feels that he has the desire of a foreigner, he has nothing to ask for to be redeemed from exile.
