'Astonishingly' in the Bible

Her uncleanness was in her skirts;She did not consider her future.Therefore she has fallen astonishingly;She has no comforter.“See, O Lord, my affliction,For the enemy has magnified himself!”

“His power will be mighty, but not by his own power;And he will corrupt and destroy in an astonishing mannerAnd [he will] prosper and do exactly as he wills;He shall corrupt and destroy mighty men and the holy people.
