2 Samuel 24:4-15

Notwithstanding the king's word prevailed against Joab, and against the captains of the host. And Joab and the captains of the host went out from the presence of the king, to number the people of Israel. And they passed over Jordan, and pitched in Aroer, on the right side of the city that lieth in the midst of the river of Gad, and toward Jazer: then they came to Gilead, and to the land of Tahtim-hodshi; and they came to Dan-jaan, and about to Zidon, and came to the strong hold of Tyre, and to all the cities of the Hivites, and of the Canaanites: and they went out to the south of Judah, even to Beer-sheba. So when they had gone through all the land, they came to Jerusalem at the end of nine months and twenty days. And 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. 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. For when David was up in the morning, the word of the LORD came unto the prophet Gad, David's seer, saying, Go 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. So 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. And David said unto Gad, I am in a great strait: let us fall now into the hand of the LORD; for his mercies are great: and let me not fall into the hand of man. So the LORD sent a pestilence upon Israel from the morning even to the time appointed: and there died of the people from Dan even to Beer-sheba seventy thousand men.
