I Chronicles 21:1-8

Now Satan stood up against Israel, and moved David to number Israel. So David said to Joab and to the leaders of the people, “Go, number Israel from Beersheba to Dan, and bring the number of them to me that I may know it.” And Joab answered, “May the LORD make His people a hundred times more than they are. But, my lord the king, are they not all my lord’s servants? Why then does my lord require this thing? Why should he be a cause of guilt in Israel?” Nevertheless the king’s word prevailed against Joab. Therefore Joab departed and went throughout all Israel and came to Jerusalem. Then Joab gave the sum of the number of the people to David. All Israel had one million one hundred thousand men who drew the sword, and Judah had four hundred and seventy thousand men who drew the sword. But he did not count Levi and Benjamin among them, for the king’s word was abominable to Joab. And God was displeased with this thing; therefore He struck Israel. So David said to God, “I have sinned greatly, because I have done this thing; but now, I pray, take away the iniquity of Your servant, for I have done very foolishly.”
