'Unprecedented' in the Bible

But if the Lord brings about something unprecedented, and the ground opens its mouth and swallows them along with all that belongs to them so that they go down alive into Sheol, then you will know that these men have despised the Lord.”

They [of Babylon] will be shocked and terrified,Pains and anguish will grip them;They will be in pain like a woman in childbirth.They will stare aghast and horrified at one another,Their faces aflame [from the effects of the unprecedented warfare].
