Deuteronomy 17:6-7 -

Only on the testimony of more than one witness could the accused be condemned (of Numbers 35:30 ); and the hand of the witnesses was to be first against him to put him to death—a rule which would tend to prevent accusations being lightly adduced, as none would venture to witness against any one unless so deeply convinced of his guilt that they were willing to assume the responsibility of inflicting on him the last penalty with their own hands. Worthy of death be put to death ; i . e . adjudged or appointed to death ; literally, the dead man shall die . מֵת , the part. of מוּת , to die, is here equivalent to בֶּן מָוֶת , son of death ( 1 Samuel 20:31 ), or אִישׁ מָוֶת , a man of death ( 1 Kings 2:26 ), i . e . one assigned to death, already the property of death, and so as good as dead. Put the evil away ; literally, consume or sweep away the evil . The verb בָּעַר means primarily to consume by burning.
