'Severely' in the Bible

A spirit seizes him, and he suddenly screams; it throws him into convulsions and causes him to foam at the mouth. It hardly ever leaves him alone, torturing him severely.

Even while the boy was coming, the demon slammed him down and threw him into a [violent] convulsion. But Jesus rebuked the unclean spirit, and healed the boy and gave him back to his father.

But He turned and rebuked them [and He said, “You do not know what kind of spirit you are;

the master of that servant will come on a day when he doesn't expect him and at an hour that he doesn't know. Then his master will punish him severely and assign him a place with unfaithful people.

And that slave who knew his master’s will and didn’t prepare himself or do it will be severely beaten.

They will flog him severely and kill him. Yet on the third day he will rise again."

Every one who falls on that stone will be severely hurt, but on whomsoever it falls, he will be utterly crushed."

who swallow up the property of widows and mask their wickedness by making long prayers. They will be punished far more severely than others."
