'Malicious' in the Bible

Malicious witnesses come forward;they question me about things I do not know.

Malicious mockers they gnashed their teeth against me.

The words of his mouth are malicious and deceptive;he has stopped acting wisely and doing good.

Even on his bed he makes malicious plans.He sets himself on a path that is not goodand does not reject evil.

Appoint a wicked man against him,And let an attacker stand at his right hand [to kill him].
