'Time of Trouble' in the Bible

which I have reserved against the time of trouble, against the day of battle and war?

But the salvation of the righteous is from the LORD. He is their stronghold in the time of trouble.

If you falter in the time of trouble, your strength is small.

Confidence in someone unfaithful in time of trouble is like a bad tooth, or a lame foot.

LORD, be gracious to us. We have waited for you. Be our strength every morning, our salvation also in the time of trouble.

You hope of Israel, its Savior in the time of trouble, why should you be as a foreigner in the land, and as a wayfaring man who turns aside to stay for a night?
