Jacob had two wives, Rachel and Leah. In addition he had children by Bilhah and Zilpah, the servants of his wives. All four of these women could be considered his wives. The Bible records the death of only one of these women, Rachel.
Then they journeyed from Bethel. When they were still some distance from Ephrath, Rachel went into labor, and she had hard labor. And when her labor was at its hardest, the midwife said to her, “Do not fear, for you have another son.”
And as her soul was departing (for she was dying), she called his name Ben-oni; but his father called him Benjamin.
So Rachel died, and she was buried on the way to Ephrath (that is, Bethlehem), and Jacob set up a pillar over her tomb. It is the pillar of Rachel’s tomb, which is there to this day.
