On the second visit Joseph made himself known to his brothers, and his family became known to Pharaoh.
In context
11Then famine and great hardship came over all Egypt and Canaan, and our ancestors could find nothing to eat. 12When Jacob heard there was grain in Egypt, he sent our ancestors there a first time. 13On the second visit Joseph made himself known to his brothers, and his family became known to Pharaoh. 14Joseph then sent for his father Jacob and all his relatives, seventy-five people in all. 15Jacob went down to Egypt, and there he died, and so did our ancestors.
