What does Genesis 45:16 mean?

Overcome with emotion, Joseph had sent everyone but his brothers out of the room before revealing himself to them (Genesis 45:1). The story soon came out, however. Even if Joseph had wanted to delay, his dramatic cries were heard by others in the household (Genesis 45:2). The rapidly circulating news was that the 11 Hebrews from Canaan were, in fact, Joseph's own brothers. Though technically a slave, Joseph was also a beloved ruler in Egypt (Genesis 41:44) credited with saving many lives from the severe famine afflicting the land.

In a heartwarming response, Pharaoh seems joyous to learn that Joseph not only had a family, but also that they were visiting in Egypt. He and all of the servants of his household seem to share this response. This is further evidence that Joseph acted honorably over the course of his life in Egypt. His reputation gained him the respect and admiration of others.
