Numbers 1:15-19 Living Bible (TLB)
2-15 “Take a census of all the men twenty years old and older who are able to go to war, indicating their tribe and family. You and Aaron are to direct the project, assisted by these leaders from each tribe”:
16 These were the tribal leaders elected from among the people.
17-19 [a] On the same day Moses and Aaron and the above-named leaders summoned all the men of Israel who were twenty years old or older to come and register, each man indicating his tribe and family, as the Lord had commanded Moses.
