R. Gamliel, R. Yehoshua, R. Elazar b. Azaryah and R. Akiva were once going to Rome, when they heard the sound of the (Roman) throng at a distance of one hundred and twenty mils — whereupon they began to cry, and, R. Akiva, to laugh. They: Why are you laughing? R. Akiva: Why are you crying? They: Shall we not cry when the idolators, who are sacrificing to the idols and bowing down to the images are dwelling in tranquility, while we — the footstool of our G-d (i.e., the Temple) has been consumed by fire and has become the habitation of wild beasts! R. Akiva: That is precisely why I am laughing. If He is so forthcoming to His angerers, how much more so to the doers of His will!
