And news will come to you of wars and talk of wars: do not be troubled, for these things have to be; but it is still not the end.

And when you have news of wars and talk of wars, do not be troubled; these things have to be, but it is still not the end.

And when news of wars and troubled times comes to your ears, have no fear; for these things have to be, but the end will not be now.

What is the cause of wars and fighting among you? is it not in your desires which are at war in your bodies?
