Isaiah 62:2

(2) Thou shalt be called by a new name . . .—So in Jeremiah 33:16, the name of the restored city is to be “Jehovah our Righteousness.” The root-thought is that the altered state is to be embodied, as in the case of Abraham and Israel, in a new name. Here, however, the effect of the promise is heightened, as in Revelation 2:17; Revelation 3:12, by the absence of the new ‘name, as something which is to transcend all experience.
