'Thoroughly' in the Bible

whose winnowing shovel is in his hand, and he will thoroughly cleanse his floor, and will gather the wheat to his storehouse, and the chaff he will burn with fire unquenchable.'

and having heard about Jesus, he sent unto him elders of the Jews, beseeching him, that having come he might thoroughly save his servant.

for I have five brothers, so that he may thoroughly testify to them, that they also may not come to this place of torment.
