2 Chronicles 23:13

and she looked, and, behold, the king stood at his pillar, at the entering in, apparently some sort of a platform near the entrance to the Temple proper, and the princes and the trumpets by the king. And all the people of the land rejoiced and sounded with trumpets, also the singers with instruments of music, rendering some of the Temple music in honor of Jehovah, and such as taught to sing praise, with the psalms used on festival occasions. Then Athaliah rent her clothes, in grief and anger, signifying her deep disgust, and said, Treason, treason! This call was a last desperate attempt to stop the proceedings, as if they were unlawful.
