(This d'var torah was delivered during Kabbalat Shabbat services.)
Vayishma Yitro — Yitro heard all of the wonders that G-d performed for Moshe and the children of Israel as they were redeemed from Egypt. How did he respond? He realized it was the proper time for Moshe to see his wife and children. His mission of redeeming the Jews was complete and his family could return to him. He was practical, efficient, and organized.
When he meets up with Moshe and Moshe tellls him what happened, Yitro's reaction is quite different: "Vayichad Yitro" — he rejoiced, and then he pronounced a blessing, "Boruch Hashem..." ! (BTW, this blessing becomes the model of our blessing Hashem for good tidings.) What was the difference? When Yitro heard about the great miracles there was no emotion, no feeling, no incredible religious experience, but when Moshe told him, the second time in fact he actually heard about the miracles, then there was rejoicing, excitement, passion, and blessing Hashem.
