Shovevim #4

Chazal teach that the sea split because of the bones of Yosef that passed through together with the Jewish people. The pasuk says that when Yosef escaped the seductions of the wife of Potiphar וינס ויצא החוצה and when the sea split it says הים ראה וינס. The same word וינס is used in order to teach us that there is a connection between Yosef's heroic act of not allowing himself to be seduced by this woman [which would have been of great personal benefit to him. Nothing like having the bosses wife on your side...] and the miracle of krias yam suf.

We see from that guarding one's bris generates miracles. If we overcome our nature for Hashem, he will change nature for us. That is the secret of the great powers of the tzadikim.
