This passage rhetorically asks "Can any one of you by worrying add a single hour to your life?" A large part of this passage consists of the phrase "You have heard it said," followed by a prescription from Mosaic Law, then the phrase "but I say unto you," followed by a refutation of the prescription. The final verse of this passage beseeches listeners to "Be perfect, therefore, as your heavenly Father is perfect."  This passage discards the metaphor of people being the (*) "salt of the earth" in favor of them being "the light of the world." The declaration "Blessed are the meek: for they shall inherit the earth" is one of this passage's Beatitudes. For 10 points, name this section of the Book of Matthew, an oration Jesus delivered at an elevated place.
