'Time of Trouble' in the Bible

Which I have reserved for the time of trouble,For the day of battle and war?

My praise will be of You in the great assembly.I will pay my vows [made in the time of trouble] before those who [reverently] fear Him.

But the salvation of the righteous is from the Lord;He is their refuge and stronghold in the time of trouble.

Like a broken tooth or an unsteady footIs confidence in an unfaithful man in time of trouble.

O Lord, be gracious to us; we have waited [expectantly] for You.Be the arm of Your servants every morning [that is, their strength and their defense],Our salvation also in the time of trouble.

“O Hope of Israel,Her Savior in time of distress and trouble,Why should You be like a sojourner (temporary resident) in the landOr like a traveler who turns aside and spreads his tent to linger [only] for a night?

“Now at that [end] time Michael, the great [angelic] prince who stands guard over the children of your people, will arise. And there will be a time of distress such as never occurred since there was a nation until that time; but at that time your people, everyone who is found written in the Book [of Life], will be rescued.
