²¹ Israel traveled, and spread 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.
