'Three Days' in the Bible

And there they were with David three days, eating and drinking; for their brethren had prepared for them;

Choose thee, either three years of famine, or three months to be destroyed before thine adversaries while that the sword of thine enemies overtaketh thee, or three days the sword of Jehovah and the pestilence in the land, and the angel of Jehovah destroying through all the borders of Israel. And now consider what word I shall bring again to him that sent me.
