Rabbi Yehoshua ben Levi - on the messiah, and when he will come, with regard to the people awaiting his arrival. Including Eliyahu (Elijah), of course. Also, the birthpangs of the messiah - how many sages want the messiah to come, but only after they themselves die, so they don't have to suffer through it. But won't the messianic era be worth it? And won't their Torah study and acts of kindness protect them? With parallels between the entrance to the land of Israel from the Exodus of Egypt, vs. the return after the Babylonian Exile.
