2 Samuel 24:10

But David’s heart struck him after he had numbered the people . And David said to the Lord , I have sinned greatly in what I have done . But now , O Lord , please take away the iniquity of your servant , for I have done very foolishly .

David was conscience-stricken after he had counted the fighting men, and he said to the Lord, “I have sinned greatly in what I have done. Now, Lord, I beg you, take away the guilt of your servant. I have done a very foolish thing.”

And David's heart smote him after that he had numbered the people. And David said unto the Lord, I have sinned greatly in that I have done : and now, I beseech thee, O Lord, take away the iniquity of thy servant; for I have done very foolishly.
