2 Samuel 24:11

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

10And 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.

11For when David was up in the morning, the word of the LORD came unto the prophet Gad, David’s seer, saying,

12Go and say unto David, Thus saith the LORD, I offer thee three things; choose thee one of them, that I may do it unto thee.

13So Gad came to David, and told him, and said unto him, Shall seven years of famine come unto thee in thy land? or wilt thou flee three months before thine enemies, while they pursue thee? or that there be three days’ pestilence in thy land? now advise, and see what answer I shall return to him that sent me.
