2 Samuel 24:4-9

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 the Jordan, and encamped in Aroer, on the right side of the city that is in the middle of the valley of Gad, and unto Jazer: then they came to Gilead, and to the land of Tahtim-hodshi; and they came to Dan-jaan, and round about to Sidon, and came to the stronghold of Tyre, and to all the cities of the Hivites, and of the Canaanites; and they went out to the south of Judah, at Beer-sheba. So when they had gone to and fro 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 numbering 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.
