'Well nigh' in the Bible

At times a spirit seizes him and he suddenly cries out. It convulses him, and makes him foam at the mouth, and does not leave him till it has well-nigh covered him with bruises.

Rouse yourself and keep awake, and strengthen those things which remain but have well-nigh perished; for I have found no doings of yours free from imperfection in the sight of My God.
