Genesis 37:28-30

Young's Literal Translation

²⁸ And Midianite merchantmen pass by and they draw out and bring up Joseph out of the pit, and sell Joseph to the Ishmaelites for twenty silverlings, and they bring Joseph into Egypt.

²⁹ And Reuben returneth unto the pit, and lo, Joseph is not in the pit, and he rendeth his garments,

³⁰ and he returneth unto his brethren, and saith, `The lad is not, and I -- whither am I going?'
