Charles Ellicott Commentary Isaiah 53:1

"Who hath believed our message? and to whom hath the arm of Jehovah been revealed?" — Isaiah 53:1 (ASV)

Who hath believed our report? ... —The question has been variously interpreted as coming from the lips of the prophet or of Israel. The former view is most persuasive, and the unusual plural is explained by his mentally associating himself with the other prophets—probably his own disciples—who were delivering the same message. The implied answer to the question may be either “None,” or “Not all.” St. Paul (Romans 10:16) adopts the latter.
