2 Samuel 24:4-9

But the king commanded Joab and the commanders of the army, so they left the king to count the Israelites. After crossing the Jordan River, they camped near Aroer on the south side of the city in the ravine. They went through Gad and on to Jazer. Then they went to Gilead and the land of Tahtim Hodshi and to Dan Jaan and around to Sidon. They went to the strong, walled city of Tyre and to all the cities of the Hivites and Canaanites. Finally, they went to southern Judah, to Beersheba. After nine months and twenty days, they had gone through all the land. Then they came back to Jerusalem. Joab gave the list of the people to the king. There were eight hundred thousand men in Israel who could use the sword and five hundred thousand men in Judah.
