1 Chronicles 21:6

⁴Nevertheless the king’s word prevailed against Joab; and Joab went out and passed through all Israel, and came to Jerusalem.

⁵And Joab gave the number of the mustering of the people to David: and all Israel was a million and a hundred thousand men that drew sword: and the sons of Judah were four hundred and seventy thousand men that drew sword.

— 1 Chronicles 21:6 —

⁷And there was evil in the sight of the Lord respecting this thing; and he smote Israel.

⁸And David said to God, I have sinned exceedingly, in that I have done this thing: and now, I pray thee, remove the sin of thy servant; for I have been exceedingly foolish.
