'Day of Trouble' in the Bible

May the Lord answer you (David) in the day of trouble!May the name of the God of Jacob set you securely on high [and defend you in battle]!

For in the day of trouble He will hide me in His shelter;In the secret place of His tent He will hide me;He will lift me up on a rock.

Call on Me in the day of trouble;I will rescue you, and you shall honor and glorify Me.”

They said to him, “This is what Hezekiah says, ‘This day is a day of distress, rebuke and disgrace; for children have come to birth, and there is no strength to deliver them.

The Lord is good,A strength and stronghold in the day of trouble;He knows [He recognizes, cares for, and understands fully] those who take refuge and trust in Him.

I heard and my whole inner self trembled;My lips quivered at the sound.Decay and rottenness enter my bones,And I tremble in my place.Because I must wait quietly for the day of distress,For the people to arise who will invade and attack us.
