Why was "tantrum" trending last week?
c.1300, "member of a militant 1st century Jewish sect which fiercely resisted the Romans in Palestine," from Late Latin Zelotes, from Greek zelotes "one who is a zealous follower," from zeloun "to be zealous," from zelos "zeal" (see zeal). Extended sense of "a fanatical enthusiast" first recorded 1630s.
a sect of Jews which originated with Judas the Gaulonite (Acts 5:37). They refused to pay tribute to the Romans, on the ground that this was a violation of the principle that God was the only king of Israel. They rebelled against the Romans, but were soon scattered, and became a lawless band of mere brigands. They were afterwards called Sicarii, from their use of the sica, i.e., the Roman dagger.
