Genesis 37:34-36

Young's Literal Translation

³⁴ And Jacob rendeth his raiment, and putteth sackcloth on his loins, and becometh a mourner for his son many days,

³⁵ and all his sons and all his daughters rise to comfort him, and he refuseth to comfort himself, and saith, `For -- I go down mourning unto my son, to Sheol,' and his father weepeth for him.

³⁶ And the Medanites have sold him unto Egypt, to Potiphar, a eunuch of Pharaoh, head of the executioners.
