2 Samuel 24:4-9

But the king’s word prevailed against Joab and the commanders of the army. So Joab and the commanders of the army went out from the presence of the king to number the people of Israel. They crossed the Jordan and began from Aroer, and from the city that is in the middle of the valley, toward Gad and on to Jazer. Then they came to Gilead, and to Kadesh in the land of the Hittites; and they came to Dan, and from Dan they went around to Sidon, and came to the fortress of Tyre and to all the cities of the Hivites and Canaanites; and they went out to the Negeb of Judah at Beersheba. 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 the sum of the numbering of the people to the king: in Israel there were 800,000 valiant men who drew the sword, and the men of Judah were 500,000.
