Genesis 35:16-18

16Then they journeyed from Bethel; and when there was still some distance to go to Ephrath (Bethlehem), Rachel began to give birth and had difficulty and suffered severely.

17When she was in hard labor the midwife said to her, “Do not be afraid; you now have another son.”

18And as her soul was departing, (for she died), she named him Ben-oni (son of my sorrow); but his father called him Benjamin (son of the right hand).
