'Grievously' in the Bible

Jerusalem has grievously sinned; therefore she is become as an unclean thing; all who honored her despise her, because they have seen her nakedness: yes, she sighs, and turns backward.

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