Musar do Liczb 33:1
אֵ֜לֶּה מַסְעֵ֣י בְנֵֽי־יִשְׂרָאֵ֗ל אֲשֶׁ֥ר יָצְא֛וּ מֵאֶ֥רֶץ מִצְרַ֖יִם לְצִבְאֹתָ֑ם בְּיַד־מֹשֶׁ֖ה וְאַהֲרֹֽן׃
Oto pochody synów Israela, którzy wyszli z ziemi Micraim, podług zastępów swych pod wodzą Mojżesza i Ahrona.
Shenei Luchot HaBerit
אלה מסעי בני ישראל . "These are the journeys of the children of Israel." Journeys are comparable to exiles in that they afford a person atonement for his sins. When someone decides to leave home in order to reside in a place where Torah learning is available, his journey may be described as at G–d's behest. It is not by accident that all the Torah scholars of earlier generations left home, i.e. exiled themselves in order to study. This principle can be summarized as צא ולמד, "leave home in order to study!"
