Numbers 1:2-4

2 “Take a census ⓐ of the entire Israelite community by their clans and their fathers’ families, [1] counting the names of every male one by one.

3 You and Aaron are to register those who are twenty years old or more by their military divisions — everyone who can serve in Israel’s army. [2] ⓑ

4 A man from each tribe is to be with you, each one the head of his ancestral family. [3] ⓒ
