TSK · 1 Chronicles 21:5

Joab reported the number of warriors to the king. In Israel there were 800,000 sword-wielding warriors, and in Judah there were 500,000 soldiers.

Joab son of Zeruiah started to count the men but did not finish. God was angry with Israel because of this, so the number was not recorded in the scroll called The Annals of King David.
