'In The Day Of Trouble' in the Bible

O Lord, my strength and my strong tower, my safe place in the day of trouble, the nations will come to you from the ends of the earth, and say, The heritage of our fathers is nothing but deceit, even false things in which there is no profit.

And will send unto Babylon fanners, that shall fan her, and shall empty her land: for in the day of trouble they shall be against her round about.
