Two answers required. They figure prominently in the opening chapter of the book of Malachi, where God reminds the Israelites that he is all-loving and above the law because he chose to save one and destroy the other. One had two concubines, Bilhah and Zilpah, while the others name translated from Hebrew means hairy. With the help of their mother, one tricked the other into giving up his birthright for a bowl of soup to fulfill the prophecy that "the last shall be first". For 10 points, name these twin sons of Rebekah and Isaac, the younger of whom fathered Joseph.
Literature

Occlusion by this astronomical body of Saggitarius Tr-180 suggests that the rate of sublimation from its surface has doubled. That sublimation may have helped to create evaporite deposits such as the Akupara and Rem maculae, which cover a surface of beta-hexagonal ice surrounding the Plain of Abatus. Its changing albedo is believed to couple with gravitational diapirism to produce the cavi of its unique terrane of Bubeme. Perhaps the most interesting surface features occur in its equatorial region, which contains fault-block mountain ranges bounded by the Ho and Lo sulci, indicating a tectonic past, and the geyser plumes Hili and Mahilani, which contribute to its thin atmosphere. FTP, name this moon of Neptune best known for its cryovolcanic eruptions and its retrograde orbit.

One work by this man features the section "The soft complaining lute," which introduced that instrument to Western music, while another of his works is a cantata discoursing on the power of music. Those works, both settings of Dryden, are his Alexander's Feast and Ode for St. Cecilia's Day. Another of his works consists of an air followed by five double variations in alternating hands called The Harmonious Blacksmith. The second suite of another of his works features the movement "Alla Hornipe", and "La Paix" and "La Rejouissance" are movements of his Music for the Royal Fireworks. For 10 points, name this composer of Water Music and the oratorio Messiah.
