Moses' father-in-law Yisro, sheik of Midian, heard about all that G-d had done for Moses and His people Israel when He brought Israel out of Egypt (Shemos 18:1)

What did Yisro hear about that made him come? The splitting of the Sea and the war with Amalek (Rashi).

Considering that Matan Torah (the giving of the Torah) is the foundation of the entire world - both spiritual and physical - would it not have been proper for Chazal to designate a full sedrah to this occurrence alone? Why was the episode with Yisro not included in Beshalach? After all, the splitting of the Sea and the war with Amalek that Yisro heard about are both contained in that sedrah.

Even more difficult to understand is Rashi's opinion that Yisro in fact did not join Bnei Yisrael until after the giving of the Torah. Why, then, did the Torah preface the giving of the Torah with Yisro's arrival?

"And Yisro heard" (Shemos 18:1). The Zohar asks: "Did only Yiro hear and the whole world not hear? Is it not written, 'the nations heard and shuddered?' The answer is that the whole world heard and were not humbled, and Yisro heard and was humbled and was drawn close to fear Hashem."

Many hear, but few really take to heart what they hear. As the Midrash Tanchuma (Yisro 2) puts it, "There are those that hear and lose, and those that hear and profit." Hearing and listening properly are the key to one's success in this world. The Midrash (Shemos Rabba 27:9) offers the following mashal on the verse, "Incline your ear and come to Me: hear and your soul shall live" (Yeshayahu 55:3)

So precious are the Jewish people to Hashem that He entices them. He said to them, "If one falls from a roof and his whole body is injured, and the doctor visits him and puts a bandage on his head, arms and legs, and all his body, he becomes totally enveloped in bandages. I am not like that. Man has two hundred and forty eight organs and one of them is the ear. If the whole body is sullied with sin, but the ear hears and listens, then the whole body receives life.

Before the Torah tells us, "And Hashem spoke," we must first learn what it means to listen. Unless there is an ear to hear, even the most powerful message from the mouth of Hashem Himself is lost. For that reason, "Yisro heard," precedes the giving of the Torah. Let us now investigate what proper hearing entails.

The Mechilta relates that prior to Matan Torah the kings of the nations heard the thunderous sounds and gathered together to seek advice from Bilaam. They were concerned that Hashem was bringing another cataclysm - if not of water, then perhaps of fire - to detroy the world. Bilaam quieted their fears by telling them that Hashem was giving His people the Torah. The kings replied, "Hashem should bless his people with peace."

Yisro heard the same thunderous noises and came to join the Jewish people and accept the Torah personally. In fact, the Mechilta relates, Yisro was the first person to exclaim 'Baruch Hashem.'

The word baruch (blessed) connotes increase and strengthening. Moshe and Bnei Yisrael were so deeply inspired by the Exodus and the splitting of the Sea that they could not imagine the effect wearing off or dissipating. Although they profusely praised and thanked Hashem, they did not see the need to use the word "baruch;" they felt no need to ask Hashem to strengthen the effect of these miracles.

Yisro, however, realized that the effect of miracles can soon be dissipated if those effects are not somehow incorporated into one's actions. He realized Amalek also heard of the splitting of the Sea, yet the impression quickly wore off and Amalek attacked Bnei Yisrael. Therefore Yisro appreciated the necessity to address Hashem with a beracha, an entreaty to intensify and increase the effect of the miracles already performed.

In contrast to Yisro, the kings of the nations were concerned personally only when they thought that the awesome sounds were harbingers of their doom. Once they were told that the sounds were the sounds of Torah, they immediately distanced themselves. They directed Hashem's blessings to His people, but did not act as if they were personally implicated. There was nothing they felt that they could gain from these sounds. Only Yisro took these sounds as a personal message and directed his blessings to Hashem so that he might personally benefit from Matan Torah.

The entire nation saw the sounds" (Shemos 20:15). Hearing alone is indiscriminate; sound is received by the ear from all directions without the need to focus or turn. Vision, on the other hand, is dependent on opening one's eyes and focusing on that which one wants to see. G-d's words had to be heard with the same intense focus employed in sight. Bnei Yisrael physically saw the sounds in order to aid their ability to listen properly.

Many sounds and sights reach our ears and eyes, but only one with the capacity to really focus can absorb their message. The Gemara relates that the turning point in the life of Rabbi Akiva was when he witnessed the erosion of a stone by water. Many observed the same thing, but only he derived the message: if water can erode stone, then Torah can change the heart. The whole world summons one with an attuned and attentive ear to the service of Hashem: "The heavens declare the glory of Hashem" (Tehillim 19:2). Look at the sky, listen to the ocean and acquire yiras shamayim: "My heart says to me in your name, 'Seek out my face'" (Tehillim 27:8)

If someone begins the Shema by repeating the word Shema twice, we silence him out of a concern that he seems to be addressing two deities (Berachos 33b). This is difficult to understand, for Shema refers to the one who is listening and not to Hashem. How then does it imply two deities? The answer is that the entire creation cries out the unity of Hashem. There is no multiplicity, only the one, unified voice of Hashem that calls out to man from all quarters. Any double hearing smacks of idolatry and duality.

Everyday a bas kol emanates from Mount Chorev and declares, "Woe to them, to the people, because of their insult to the Torah" (Pirkei Avos 6:2). The commentaries explain that the giving of the Torah did not stop, as it says, "A great sound that did not cease" (Devarim 5:19). One with an attuned ear hears the voice of Hasem giving the Torah continually, as the basis of all of creation. When the voice is not heard, then the bas kol (echo) goes out proclaiming the disgrace to Torah.

The Mechilita (see also Kiddushin 22b) describes the piercing of the earlobe of the Jewish slave as a punishment for his failure to hear and heed the ongoing commandment, "Do not steal." It might be asked, however, why we pierce the earlobe, a mere piece of cartilage, and not the eardrum which failed to hear.

Chazal tell us that the outer ear serves as a funnel to collect the sound waves and direct them to the inner ear. The problem of the slave was not that he did not hear on Sinai that we are all to subjugate ourselves to Hashem alone. But he failed to hear the command as if it were directed to him and him alone. His outer ear failed to funnel those words to him, and thus bears the blemish. He heard G-d's voice but did not experience it as if G-d was speaking to him.

"Kayin spoke with his brother Hevel, and when they were in the field, Kayin arose and smote Hevel, his brother" (Breishis 4:8). Many midrashim discuss what exactly Kayin said to Hevel. Ibn Ezra notes that according to the simple understanding of the verse, Kayin repeted to Hevel the admonition he had just heard from Hashem: "If you will improve, then you will be forgiven, and if not, the sin crouches by the entrance, and it desires you, but you can dominate it" (Breishis 4:7). How can these words of mussar to Hevel have led to murder? They should have prevented the murder.

Like most people, Kayin heard the mussar as directed at everybody but him. Since Hevel was the only person around, he assumed it was intended for him. So Kayin "said over" the mussar to Hevel rather than mulling over its implications for him. Not only did it fail to prevent the murder, but by suggesting to Kayin that Hevel was in need of mussar, it may have even aroused his animosity.

When I was younger and more naive, I assumed that my Shabbos drashah would be an effective medium to reach members of my congregation in need of reproof. Inevitably, the targeted individual(s) would approach me after davening and tell me, "Rabbi, you really gave it to them, I hope the ones who needed to hear got the message." "Obviously," I thought to myself, "they did not."

Mussar is only effective if one takes it personally. Even if one hears it directly from Hashem Himself, as Kayin did, unless one recognizes that it is directed at him, the mussar is useless.

A truly sensitive person will always hear any reproof as directed at him or her. I once addressed a group of three hundred and fifty complete strangers in Johannesburg and spoke about modesty and the problems of certain forms of dress. After the shiur, I recevied the following note:

Dear Rabbi Leff,
I want to apologize for the manner in which I dressed for the shiur. I don't usually wear this type of clothing, but in my rush to the shiur, I grabbed what was available. I know you were referring to me, and I promise not to repeat this error.
