"In the LXX, dikaioun is a Forensic term. Yet it does not have a predominate negative connotation ("to condemn") as in the Greek, but is constantly used in the postive sense of "to pronounce righteous," "to justify," "to vindicate." The forensic element is even stronger in the LXX than in the Masoretic text."
