Genesis 37:18-22

And when they saw him afar off, even before he came near unto them, they conspired against him to slay him.

And they said one to another, Behold, this dreamer cometh.

Come now therefore, and let us slay him, and cast him into some pit, and we will say, Some evil beast hath devoured him: and we shall see what will become of his dreams.

And Reuben heard it, and he delivered him out of their hands; and said, Let us not kill him.

And Reuben said unto them, Shed no blood, but cast him into this pit that is in the wilderness, and lay no hand upon him; that he might rid him out of their hands, to deliver him to his father again.
