These three פרשיות speak basically of one subject, namely the Tabernacle and those who camped around it, i.e. altogether three camps. The first of these camps is the מחנה שכינה, the Tabernacle itself. The second camp is the מחנה לויה which surrounds the Tabernacle on all sides. Here the Levites were encamped. The third camp is the מחנה ישראל, the camp of the twelve tribes with their four flags. (Three tribes would always be grouped together facing one direction). We focus in our commentary on all these three פרשיות together because the name of this chapter is aptly called שלושה מחנות.

There is not a single commandment in Parshat Bamidbar.
