Genesis 37:19-22

They said to one another, “Look, here comes this dreamer. Now then, come and let us kill him and throw him into one of the pits (cisterns, underground water storage); then we will say [to our father], ‘A wild animal killed and devoured him’; and we shall see what will become of his dreams!” Now Reuben [the eldest] heard this and rescued him from their hands and said, “Let us not take his life.” Reuben said to them, “Do not shed his blood, but [instead] throw him [alive] into the pit that is here in the wilderness, and do not lay a hand on him [to kill him]”—[he said this so] that he could rescue him from them and return him [safely] to his father.
