The fourteen cows on the left (seven fat, seven starving) are from the dream that Joseph interprets for Pharaoh. The papyrus at the bottom right depicts Joseph with his Coat Of Many Colors, a gift from his father Jacob. His eleven brothers are annoyed at Joseph's showoff behavior, and soon they will dump him in a well. But everything works for good, and eventually Joseph becomes Prime Minister (or grand vizier, or whatever) of Egypt. His father's coat may have been pretty snazzy, but it was nothing like these threads. I think he must've borrowed them from Pharaoh.
