Genesis 45

Ah, the finale!  Joseph put on quite a show, and I think it would be priceless to see the faces of his brothers when he revealed himself.  In fact, I bet a good MasterCard commercial could be made out of that:

"Being sold into slavery: 0 silver.

Being promoted to Pharaoh's side: 1,000 silver.

Saving Egypt from famine: 1,000,000 silver.

Seeing your brother's faces when they think you will kill them: Priceless."

Or something like that :)  We can tell from the rest of the passage that his biological brother Benjamin was particularly close and important to Joseph, and the reunion with his father in the next chapter promises to be good as well.
