Genesis 35:21

18 And as her soul was departing (for she was dying), she called his name Ben-oni; but his father called him Benjamin. 19 So Rachel died, and she was buried on the way to Ephrath (that is, Bethlehem), 20 and Jacob set up a pillar over her tomb. It is the pillar of Rachel’s tomb, which is there to this day. 21 Israel journeyed on and pitched his tent beyond the tower of Eder. 22 While Israel lived in that land, Reuben went and lay with Bilhah his father’s concubine. And Israel heard of it. Now the sons of Jacob were twelve. 23 The sons of Leah: Reuben (Jacob’s firstborn), Simeon, Levi, Judah, Issachar, and Zebulun. 24 The sons of Rachel: Joseph and Benjamin.
