These were the men registered by Moses and Aaron and the twelve leaders of Israel, all listed according to their ancestral descent.
Joab reported the number of people to the king. There were 800,000 capable warriors in Israel who could handle a sword, and 500,000 in Judah.
They were registered by families—all the men of Israel who were twenty years old or older and able to go to war.
Not one person on this list had been among those listed in the previous registration taken by Moses and Aaron in the wilderness of Sinai.
