Joseph’s brothers must have very sore backs by now. Since they first came to Egypt looking for food they have repeatedly bowed low, even prostrated themselves before their brother. They hated his prophetic dreams, but they cannot escape their fulfilment.

It was one thing, in fulfilment of Joseph’s dreams, for his brothers to bow down before him; quite another thing for Judah to prostrate himself before his brother Joseph and offer himself up in place of Benjamin.

Just as Judah had left his personal seal and staff with his daughter-in-law Tamar (Gen 38), so Joseph now leaves his cloak with Potiphar’s wife. But how different Joseph is to his brother! Just as when his brothers stripped his cloak off him and threw him into a pit, so now, Joseph is an innocent victim.
