'Three Days' in the Bible

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

Either three years' famine; or three months to be destroyed before thy foes, while the sword of thy enemies overtaketh thee; or else three days the sword of the LORD, even the pestilence, in the land, and the angel of the LORD destroying throughout all the borders of Israel. Now therefore advise thyself what word I shall bring again to him that sent me.
