Complete Jewish Bible

¹⁶ These were the ones called from the assembly, the chiefs of their fathers’ clans and heads of thousands in Isra’el. ¹⁷ So Moshe and Aharon took these men who had been designated by name; ¹⁸ and, on the first day of the second month, they gathered the whole assembly to state their genealogies by families and clans and recorded the names of all those twenty years old and over, as well as their total numbers.
