⁴⁴ These [are] those numbered, whom Moses numbered -- Aaron also, and the princes of Israel, twelve men -- each for the house of his fathers, they have been.

⁴⁵ And they are, all those numbered of the sons of Israel, by the house of their fathers, from a son of twenty years and upward, every one going out to the host in Israel,

⁴⁶ yea, all those numbered are six hundred thousand, and three thousand, and five hundred and fifty.
