'Troubles' in the Bible

Do not be over-anxious, therefore, about to-morrow, for to-morrow will bring its own cares. Enough for each day are its own troubles.

But all these things are the first of the troubles.

"Immediately after the troubles of those days, "The sun will be darkened, the moon will not give its light, the stars will fall from the sky, and the powers of heaven will be shaken loose.'
