"Bar Koziva ruled two-and-a-half years. He declared to the Rabbis: I am the awaited Messiah! They said to him: Regarding the Messiah it is written that 'he sniffs and judges'. Let us see for ourselves whether he can 'sniff and judge'! Once they saw that he could not 'sniff and judge', they killed him."
-- Talmud Bavli, Sanhedrin 93b
The
powers of the Messiah are enhanced by becoming a son of Aaron the
priest and performing the incense service in the Tent of Meeting.
