1 Chronicles 21:3-7

But Joab said, “May the Lord add to His people a hundred times as many as they are! My lord the king, are they not all my lord’s servants? Why does my lord seek this thing? Why should he be a cause of guilt to Israel?”

Nevertheless, the king’s word prevailed against Joab. Therefore, Joab departed and went throughout Israel, and came to Jerusalem.

Then Joab gave the number of the census of the people to David. Israel was 1,100,000 men in all who drew the sword; and Judah was 470,000 men who drew the sword.

But he did not count Levi and Benjamin among them, because the king’s command was abhorrent to Joab.

Now God was displeased with this thing, so He struck Israel.
