'Suddenly' in the Bible

I see one destruction after another taking place, so that the whole land lies in ruins. I see our tents suddenly destroyed, their curtains torn down in a mere instant.

Their widows will become in my sight more numerous than the grains of sand on the seashores. At noontime I will bring a destroyer against the mothers of their young men. I will cause anguish and terror to fall suddenly upon them.

But suddenly Babylonia will fall and be destroyed. Cry out in mourning over it! Get medicine for her wounds! Perhaps she can be healed!
