Administration of the Tribes of Israel (1CH 27:23-24)

[27:23] King David did not take a census of the people who were under the age of twenty, because of the Lord's promise to make the people of Israel as numerous as the stars in the sky.

[27:24] Joab, whose mother was Zeruiah, began to take a census, but he did not complete it. God punished Israel because of this census, so the final figures were never recorded in King David's official records.
