1 Chronicles 21:4-8

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.

David said to God, “I have sinned greatly, by doing this thing. But now, please overlook Your servant’s guilt, for I have behaved very foolishly.”
