Genesis 37:21-24

But when Reuben heard of their scheme, he came to Joseph’s rescue. “Let’s not kill him,” he said. “Why should we shed any blood? Let’s just throw him into this empty cistern here in the wilderness. Then he’ll die without our laying a hand on him.” Reuben was secretly planning to rescue Joseph and return him to his father. So when Joseph arrived, his brothers ripped off the beautiful robe he was wearing. Then they grabbed him and threw him into the cistern. Now the cistern was empty; there was no water in it.
