1 Chronicles 21:5

And Joab gave the total count of the census of the people to the king; and there were in Israel 800,000 valiant men who drew the sword, and the men of Judah were 500,000 men.

But David did not take up a count of those twenty years of age and under, because Yahweh had said He would multiply Israel as the stars of heaven.

Joab the son of Zeruiah had begun to number them, but did not finish; and because of this, wrath came upon Israel, and this count was not included in the total count of the chronicles of King David.
