Binyanim Did Know II

Previously (way back when) I had wondered if Binyamin actually knew that Yosef had been sold.

Well, I recently came across a Medrash in Parshas VaYeitzei (71:5) that says because Rochel grabbed onto the midda of shtikah (by not telling Ya'akov that he was marrying Leah) she was zocheh to have descendents who keep secrets. One of the people the Medrash mentions is Binyamin who knew that Yosef had been sold but did not say anything. (The other two are Shaul and Esther. Compare this to the gemara Megilla 13B).
