Numbers 2:32-34 - Summary
32 Here is a summary of the census of the Israelis according to the tribes of their ancestral houses: All the divisions in the camps numbered 603,550, 33 but the descendants of Levi were not numbered along with the other Israelis, just as the LORD had commanded Moses.
34 So the Israelis did everything just as the LORD had commanded Moses; that is, they encamped under their standard as each person traveled with his own tribe and ancestral house.
