Matthew 24:5 - Ellicott's Commentary On The Whole Bible

Many shall come in my name, saying, I am Christ. — Better, the Christ. No direct fulfilments of this prediction are recorded, either in the New Testament, or by Josephus, or other historians. Bar-Cochba (the “son of the star”), who claimed to be the “Star” of the prophecy of Balaam (Numbers 24:17), is often named as a fulfilment; but he did not appear till A.D. 120 — nearly 50 years after the destruction of Jerusalem. In the excited fanaticism of the time, however, it was likely enough that such pretenders should arise and disappear, after each had lived out his little day, and fill no place in history. The “many antichrists, i.e., rival Christs, of 1 John 2:18, may point to such phenomena; possibly, also, the prophecy of 2 Thessalonians 2:4. Theudas (the last rebel of that name — not the one named in Acts 5:36, but by Josephus, Ant. xx. 5), or “the Egyptian” of Acts 21:38, may possibly have mingled Messianic claims with their pretensions, but there is no evidence of it.
