2 Samuel 24:1-10

Now again the anger of the LORD burned against Israel, and He incited David against them to say, “Go, count [the people of] Israel and Judah.” So the king said to Joab the commander of the army who was with him, “Go now through all the tribes of Israel, from Dan [in the north] to Beersheba [in the south], and conduct a census of the people, so that I may know the number of the people.” But Joab said to the king, “May the LORD your God add to the people a hundred times as many as there are, and let the eyes of my lord the king see it; but why does my lord the king want to do this thing?” Nevertheless, the king’s word prevailed against Joab and the commanders of the army. So they went from the king’s presence to take a census of the people of Israel. They crossed over the Jordan and camped in Aroer, on the south side of the city which is in the middle of the river valley [of the Arnon] toward Gad, and on toward Jazer. Then they came to Gilead and to the land of Tahtim-hodshi, and they came to Dan-jaan and around to Sidon, and they came to the stronghold of Tyre and to all the cities of the Hivites and Canaanites, and they went out to the south of Judah, to Beersheba. So when they had gone about through all the land [taking the census], they came to Jerusalem at the end of nine months and twenty days. And Joab gave the sum of the census 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. But David’s heart (conscience) troubled him after he had counted the people. David said to the LORD, “I have sinned greatly in what I have done. But now, O LORD, please take away the sin of Your servant, for I have acted very foolishly.”
