'Downfall' in the Bible

All my haters are talking secretly together against me; they are designing my downfall.

My downfall is ever before me, and I am covered with the shame of my face;

What cause have I for fear in the days of evil, when the evil-doing of those who are working for my downfall is round about me?

O Lord, take me out of the hands of sinners; keep me safe from the violent man: for they are designing my downfall.
