'Grievously' in the Bible
My heart is grievously pained within me, and the terrors of death have fallen upon me.
Jerusalem has grievously sinned; therefore she has become an unclean thing and has been removed. All who honored her despise her, because they have seen her nakedness; yes, she herself groans and sighs and turns [her face] away.
Behold, O Lord, how distressed I am! My vital parts (emotions) are in tumult and are deeply disturbed; my heart cannot rest and is violently agitated within me, for I have grievously rebelled. Outside the house the sword bereaves, at home there is [famine, pestilence] death!
But the house of Israel rebelled against Me in the wilderness; they walked not in My statutes and they despised and cast away My judgments, which, if a man keeps, he must even live in and by them; and they grievously profaned My Sabbaths. Then I thought I would pour out My wrath on them in the wilderness and uproot and consume them.
