'Violent' in the Bible

A violent windstorm came up, and the waves began breaking into the boat, so that the boat was rapidly becoming swamped.

For he did not [really] know what to say because they were terrified [and stunned by the miraculous sight].

And they took him to him: and when he saw him, the spirit in him straight away became violent; and he went down on the earth, rolling about and streaming at the lips.
