6 And you will hear of wars and rumors of wars. See that you are not troubled; for all[a] these things must come to pass, but the end is not yet. 7 For nation will rise against nation, and kingdom against kingdom. And there will be famines, pestilences,[b] and earthquakes in various places. 8 All these are the beginning of sorrows.

5 And Jesus, answering them, began to say: “Take heed that no one deceives you. 6 For many will come in My name, saying, ‘I am He,’ and will deceive many. 7 But when you hear of wars and rumors of wars, do not be troubled; for such things must happen, but the end is not yet. 8 For nation will rise against nation, and kingdom against kingdom. And there will be earthquakes in various places, and there will be famines and troubles.[a] These are the beginnings of sorrows.
