'Grievously' in the Bible

Jerusalem hath grievously sinned; therefore she is become as an unclean thing; All that honored her despise her, because they have seen her nakedness: Yea, she sigheth, and turneth backward.

Behold, O Jehovah; for I am in distress; my heart is troubled; My heart is turned within me; for I have grievously rebelled: Abroad the sword bereaveth, at home there is as death.
