2 Samuel 24:8-10

21st Century King James Version

⁸ So when they had gone through all the land, they came to Jerusalem at the end of nine months and twenty days.

⁹ And Joab gave the sum of the number of the people unto the king: and there were in Israel eight hundred thousand valiant men who drew the sword, and the men of Judah were five hundred thousand men.

¹⁰ And David’s heart smote him after he had numbered the people. And David said unto the Lord, “I have sinned greatly in what I have done. And now, I beseech Thee, O Lord, take away the iniquity of Thy servant, for I have done very foolishly.”
