'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 of Jehovah; He is their stronghold in the time of trouble.

Confidence in an unfaithful man in time of trouble Is like a broken tooth, and a foot out of joint.

O Jehovah, be gracious unto us; we have waited for thee: be thou our arm every morning, our salvation also in the time of trouble.

O thou hope of Israel, the Saviour thereof in the time of trouble, why shouldest thou be as a sojourner in the land, and as a wayfaring man that turneth aside to tarry for a night?

And at that time shall Michael stand up, the great prince who standeth for the children of thy people; and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.
