The seventh time that Yosef cries in his serialized Torah drama is when the brothers approach him after Yaakov dies, saying (in Yaakov's name) that he should not take revenge for what they did to him.
He is, perhaps, struck by how wealth and power are a facade and that all the power in the world is no match for the strength inherent in being connected to your family. He cries, as he realizes, that while he seems to be the one who has what they lack, and that he is the one providing for them, the opposite may be more true. They have something he always wanted, each other.
