2 Chronicles 23:11-13

Then they brought out the king’s son and put the crown on him, and gave him the testimony [a copy of the Mosaic Law] and made him king. And Jehoiada and his sons anointed him and said, “Long live the king!” [Ex 25:16, 21] When Athaliah heard the sound of the people running and praising the king, she went into the house of the LORD to [see what] the people [were doing]. She looked, and there was the [young] king, standing by his pillar at the entrance, and the captains and the trumpeters were beside him. And all the people of the land were rejoicing and blowing trumpets, and the singers with their musical instruments were directing the [singing of] praise. Then Athaliah tore her clothes and cried, “Treason! Treason!”
