'Wars' in the Bible

And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet.

And when ye shall hear of wars and rumours of wars, be ye not troubled: for such things must needs be; but the end shall not be yet.

But when ye shall hear of wars and commotions, be not terrified: for these things must first come to pass; but the end is not by and by.

From whence come wars and fightings among you? come they not hence, even of your lusts that war in your members?
