sechel: The gemarah says is sanhedrin the the talmidim all said their rebbe is THE moshiach
Not again! Please! That MAY be what they meant, but neither the gemoro there nor Rashi – כל אחד הי’ דורש אחר שמו -says that they said their Rebbe is Mashiach. Look again, and learn it as if you have never learnt it before without any preconceptions.
