'Severely' in the Bible

Because his father {oppressed severely}; {he stole from his brother}; [that] which [is] not good he did in the midst of his people, and look! He will die through his guilt.

They severely oppress the people of the land, and {they committed robbery}, and they mistreated [the] needy and [the] poor, and they oppressed the alien {without} justice.

I'll take vengeance on them, punishing them severely in my anger. They'll know that I am the LORD when I take my vengeance on them."'"
