חסידות אויף איוב 32:8

Therefore it says, "Tomorrow I shall bring locusts (arbeh)," which stands for "Truly there is spirit in mankind" (Job 32:8) [the first letters of which spell out arbeh], and this is music, which is a kind of spirit. In those days, therefore, the music and melody of the highest faith will be revealed, and it will negate all heresies, even those deriving from the empty void.
