Tossup

Each verse of a traditional Passover song asks “who knows” one of these things. In early tarot (“TAIR-oh”) decks, such as the Tarot of Marseilles, The Fool is the only card lacking one of these objects. Through gematria (“geh-MAH-tree-uh”), one of these things associated with the Beast of Revelation got identified with (10[1])Nero’s (10[1])name. (10[2])In a book whose English title is named after these things, (10[1])God told one prophet to set a fiery serpent on a pole. That book whose English (10[1])title is named after these things features twelve spies sent into Canaan and begins at Mount Sinai. (10[1])That Biblical book’s English title is named after these things due to censuses taken of the Israelites by Moses. (10[2])For 10 points, the English title of the fourth book of the Hebrew Bible is named after what things, which include 666? ■END■

ANSWER: numbers [or numeri; or arithmoi; or Book of Numbers; or Liber Numeri; prompt on Bemidbar by asking “what is its English title?”] (While The Fool was unnumbered in early tarot decks, it is usually assigned the number 0 in modern decks.)
