Two Paths

Rashi (10:31) says that Yisro elected not to stay and enter Eretz Yisroel because he was told that converts do not get a portion in Eretz Yisroel.  Would Yisro, who gave up so much turn back just over a piece of land?  And what was Moshe's request והיית לנו לעינים?  And why is the name חובב used to describe Yisro here? 

Rav Hirsch explains the usage of חובב for Yisro השורש ״חבב״, השכיח בלשון חכמים במובן של אהבה והערכה, נמצא בתנ״ך רק פעם אחת: ״אף חובב עמים על קדשיו בידך״ (דברים לג, ג). נראה ש״חבב״ קרוב ל״חוב״, שאף הוא שכיח בלשון חכמים ונמצא בתנ״ך רק פעם אחת: ״חֲבֹלָתוֹ חוֹב יָשִׁיב״ (יחזקאל יח, ז). לפי זה ״חבב״ יורה על אהבה מחייבת ועל אהבה הנובעת מתחושת חובה. לפי זה, ״חוֹבָב״ (השווה הצורות ״שׁוֹבָב״, ״שׁוֹלָל״, ״עוֹלָל״, שכולם באים בלשון בלתי־פעילה) הוא אדם שאהבת ה׳ מחייבת אותו, אדם שחש שהוא מחוייב לה׳ על ידי אהבה זו.  This short few pessukim are describing a debate Yisro was having in which was better to serve and demonstrate his love for Hashem.  The Sifsay Kohan interprets והיית לנו לעינים that people would see Yisro came and joined the Jews and they would be encouraged to join as well.  Moshe was encouraging Yisro to join with Klal Yisroel so that people would see that it is possible and correct to leave all of one's stature and greatness behind and join those following Hashem.  However, Yisro understood that if he is not given a portion of land that means that is not his mission.  It is not his job to sit and let others see but he must go beck to the land of the heathens and encourage them to join his ways. There are those meant to live in Eretz Yisroel but there are those that must tread another path sharing their journey with the world around them.
