Genesis 37:20-22

20Come now, let us kill him and throw him into one of the pits. Then we will say that a fierce animal has devoured him, and we will see what will become of his dreams."

21But when Reuben heard it, he rescued him out of their hands, saying, "Let us not take his life."

22And Reuben said to them, "Shed no blood; throw him into this pit here in the wilderness, but do not lay a hand on him"—that he might rescue him out of their hand to restore him to his father.
