וְאִם־לֹ֥א יֵעָלֶ֖ה הֶעָנָ֑ן וְלֹ֣א יִסְע֔וּ עַד־י֖וֹם הֵעָלֹתֽוֹ׃
Но если облако не было взято, то они путешествовали не до того дня, как оно было взято.

וענן ה' עליהם יומם ולילה, “and the cloud of the Lord was above them both by day and by night. Regarding Rashi’s commentary that there were seven clouds during theIsraelites’ journeys, they were not all mentioned in a single paragraph, as pointed out in Torat Kohanim. Four enveloped them from the four directions of the globe, and two from above and below. The seventh traveled ahead of them. This latter one is the one mentioned here. The others are mentioned in Numbers 14,14, Numbers 9,19, Exodus 40,36 and 40,37. According to the view of Rabbi Yehudah, there were 13 such clouds, 2 in each direction of the globe, two above and two below, and one in front of them. According to the opinion of Rabbi Yoshia, there were only four clouds, whereas according to the opinion of Rabbi Yehudah hanassi, there were only two such clouds.
