'Reversals' in the Bible

So Gad went to David and asked him, "Shall seven years of famine come to your land, or three months of reversals while you flee from your enemies as they pursue you, or three days of pestilence in your land? Decide right now what I am to answer to the one who sent me."

Either three years of famine, or three months of reversals as you are swept away by your enemies while the sword of your enemies overtakes you, or three days with the sword of the LORD, consisting of pestilence infecting the land, with the angel of the LORD wreaking destruction from border to border throughout all of Israel.' Decide right now what I am to answer to the one who sent me."
