Rashi on Exodus 40:38/רש"י על שמות מ׳:ל״ח

1לעיני כל בית ישראל בכל מסעיהם [THE CLOUD WAS ON THE TABERNACLE] … IN THE SIGHT OF ALL THE HOUSE OF ISRAEL, THROUGHOUT ALL THEIR JOURNEYS — At every מסע which they made (according to Rashi this means: at every station at which they stopped) the cloud rested upon the Tabernacle in the place where they encamped. A place where they encamped is also called מסע (the literal meaning of which is “journey”). Similar is, (Genesis 13:3) “And he went on to his resting places (למסעיו)“ (cf. Rashi on this verse); similar also is, (Numbers 33:1) “These are the מסעי” — “the places of encampment”. Because from the place of encampment they always set out again on a new journey therefore all the different stages of their journeys (including the places where they encamped) are called מסעות.
