Remembering earlier in the story, Rachel's father Laban had chased
after Jacob and Rachel, partly because she had stollen her fathers
household gods; Idols... God took her life because He did not want her
bringing pagan idols into Abraham' and Jacob's tents AND teaching her
children to worship pagan gods...
  It is also said that while Jacob loved Rachel, he needed Leah... She
bore ten of the fathers of Israel...
