Rachel
    n 1: (Old Testament) the second wife of Jacob and mother of
         Joseph and Benjamin

Easton's 1897 Bible Dictionary:

Rachel
   ewe, "the daughter", "the somewhat petulant, peevish, and
   self-willed though beautiful younger daughter" of Laban, and one
   of Jacob's wives (Gen. 29:6, 28). He served Laban fourteen years
   for her, so deep was Jacob's affection for her. She was the
   mother of Joseph (Gen. 30:22-24). Afterwards, on Jacob's
   departure from Mesopotamia, she took with her her father's
   teraphim (31:34, 35). As they journeyed on from Bethel, Rachel
   died in giving birth to Benjamin (35:18, 19), and was buried "in
   the way to Ephrath, which is Bethlehem. And Jacob set a pillar
   upon her grave". Her sepulchre is still regarded with great
   veneration by the Jews. Its traditional site is about half a
   mile from Jerusalem.

     This name is used poetically by Jeremiah (31:15-17) to denote
   God's people mourning under their calamities. This passage is
   also quoted by Matthew as fulfilled in the lamentation at
   Bethlehem on account of the slaughter of the infants there at
   the command of Herod (Matt. 2:17, 18).
