'In The Day Of Trouble' in the Bible

[To the Chief Musician. A Psalm of David.] The LORD hear you in the day of trouble; the name of the God of Jacob defend you;

And call upon me in the day of trouble: I will deliver you, and you shall glorify me.

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

The LORD is good, a stronghold in the day of trouble; and he knows them that trust in him.

When I heard, my body trembled; my lips quivered at the voice: rottenness entered into my bones, and I trembled in myself, that I might rest in the day of trouble: when he comes up unto the people, he will invade them with his troops.
