Numbers 2:1-2 Now the LORD spoke to Moses and to Aaron, saying, 2 “The sons of Israel shall camp, each by his own standard, with the banners of their fathers’ households; they shall camp around the tent of meeting at a distance.

It’s these first few chapters that give Numbers it’s name. Once you get past this bit, the book is quite interesting.

I will say that we would do well to embrace our forefathers and reflect on their faith (regardless of the faith tradition they came from). Knowledge of those how came before us is a valuable thing. Planting their banner and honoring their standard can be good.
