2 Samuel 24:3, 18

But Joab said to the king, “Now may the LORD your God add to the people a hundred times as many as they are, while the eyes of my lord the king still see; but why does my lord the king delight in this thing?”

So Gad came to David that day and said to him, “Go up, erect an altar to the LORD on the threshing floor of Araunah the Jebusite.”
