What does Genesis 45:15 mean?

Joseph has just embraced his younger brother Benjamin (Genesis 35:24), and both have wept together at their unexpected reunion (Genesis 45:1–14). Now Joseph kisses, embraces, and cries on all of his other ten brothers. He expresses physically what his words have implied: He is not holding their crime against them. He truly believes, though they intended harm, God used their terrible treatment of him to save their family and their future. This very moment was the purpose of all his suffering.

Though Benjamin wept with Joseph, we're not told that the other brothers cry. Perhaps they are too stunned, still processing everything Joseph has revealed to them. They do, however, begin to talk to him, likely asking questions, trying to fully comprehend everything that has happened to Joseph over the last two decades.
