R. Shimon says: Why is it called "bread of affliction"? Because of the affliction that they suffered in Egypt.
"For in haste did you leave the land of Egypt.": I might think the haste of both Israel and Egypt. It is, therefore, written (Shemoth 11:7) "And against all the children of Israel a dog shall not sharpen its tongue" — Say, then, it was only Egypt that was in haste.
"so that you remember the days of your leaving the land of Egypt": This is as R. Elazar b. Azaryah said: I am like one who is seventy years old, and I did not merit reciting the exodus from Egypt at night (in the blessing after the Shema) until Ben Zoma expounded "so that you remember your leaving the land of Egypt all the days of your life." "the days of your life" — the days; "all the days of your life" — the nights. The sages say: "the days of your life" — this world; "all the days of your life" — including the days of the Messiah.
