Responsa zu Tehillim 49:14

Such is the fate of those who are self-confident, the end of those pleased with their own talk. Selah. to have their singing voices heard; they smash the Hebrew words into pieces, and one cannot understand properly what they are saying – just a voice with the mispronounced words.
