Sicarii were killers who were a splinter group of theZealots during the time leading up to the destruction ofJerusalem by theRoman General Titus. Their name derives from a work that means "dagger". They hid in groups of people who supported Roman rule and then pulled their daggers and killed people. Then they ran away and hid.Judas Iscariot, one of theTwelve Apostles ofJesus in theNew Testament, was believed by some to be a sicarius.[1]
