'Day of Trouble' in the Bible

For it is a day of trouble, and of treading down, and of perplexity, from the Lord, LORD of hosts, in the valley of vision, a breaking down of the walls, and a crying to the mountains.

And they said to him, Thus says Hezekiah, This day is a day of trouble, and of rebuke, and of blasphemy, for the sons have come to the birth, and there is not strength to bring forth.
