Musar zu Bereschit 43:14

Rabbi Oshiyah in Bereshit Rabbah 92, 3 comments that when Jacob said to his sons in Genesis 43,14 prior to their second descent to Egypt: "May the Lord Shaddai grant you mercy when you appear before the man, etc.," he alluded to the 4 exiles. The word "the man," i.e. האיש, in that verse referred to G–d who is described as איש מלחמה in the song the Israelites sang after crossing the sea of reeds (Exodus 15,3). When Jacob continued "and he will send to you your brother," [the Midrash presumably reads the word Achichem, "your brother," singular as Acheychem, "your brothers," Ed.] this refers to the Ten Tribes; the words: "the other one and Benjamin," refer to Benjamin and Yehudah. When Jacob (in his capacity of the nation's founding father) continued: "as for me, if I am to be bereaved, I am to be bereaved," refers to the two destructions of the first and second Temple respectively. Jacob implies that there will not be a third destruction.
