Genesis 37:19-22

And they said one to another, Behold, this dreamer cometh. Come now therefore, and let us slay him, and cast him into one of the pits, and we will say, An evil beast hath devoured him: and we shall see what will become of his dreams. And Reuben heard it, and delivered him out of their hand, and said, Let us not take his life. And Reuben said unto them, Shed no blood; cast him into this pit that is in the wilderness, but lay no hand upon him: that he might deliver him out of their hand, to restore him to his father.
