David, tempted by Satan, forceth Joab to number the people. The number of the people being brought, David repenteth of it. David, having three plagues propounded by Gad, chooseth the pestilence. After the death of seventy thousand, David by repentance preventeth the destruction of Jerusalem. David, by Gad's direction, purchaseth Ornan's threshingfloor: where having built an altar, God giveth a sign of his favour by fire, and stayeth the plague. David sacrificeth there, being restrained from Gibeon by fear of the angel.
