-Moses scolded his nephews saying, "Madua Lo Achaltem Es Hachatas Bemakom Hakadosh" - "Do you know that you did not eat the sin offering in the holy place" (Leviticus 10:17).
The first letters of the Hebrew words stand for "MaLEy AHaVaH" - "filled with love" - to teach that Moses' anger was only exterior, but within his heart he was filled with true brotherly love.

-"And Moses heard and it became good in his eyes" (Leviticus 10:20),
What does it mean "it became good"? It means that Moses was always saying the words of Torah and Aaron was always hearing them. However, this time the verse says "and Aaron said that today is the day", therefore the scripture states that Moses heard, because this time he was hearing the Torah. It became good in his eyes, because he saw that it is better to hear words of Torah than to say them himself.

-"And all wild animals that walk on four paws are unclean to eat" (Leviticus 11:27)
Why does the Torah have to write this? None of these animals chew cud nor do they have cloven hooves, since they walk on paws. One must say that this is hinting to a teaching. Chewing cud hints to the concept that a person must constantly meditate upon his past actions, as if to say he is "chewing it over". He must always contemplate his deeds. This is like ruminant animals that eat the same food again that they have already eaten. Also, the Hebrew word for cud, "gerah" is equal in Gematria to the name "Yitzchak" (Isaac). This means that a person must be in awe of G-d while eating, as Isaac was known for his pious fear of G-d, inasmuch as G-d is referred to in Scripture as the "Fear of Isaac". This is hinted to by the fact that the Sacred Table was located on the northern side of the Holy Temple, as Kabbalah teaches that "north" is a reference to awe. Split hooves hint to the need for a person to recount his steps, for the Sages teach that a person must always be afraid that he is going in the wrong spiritual direction in life, and be careful to go on the proper path. All that walk on paws hints to the type of person who believes, G-d forbid, that all of his strength is in his own hands, and that he is responsible for all of his accomplishments, ignoring the Hand of G-d in his personal life. One must rather believe that all of his livelihood comes only from the mercy that the L-rd has upon him. This is further emphasized by the usage of the term "walk", that one must realize that even one's spiritual goodness does not come from his own strength, but are also a gift from G-d, as is taught in the book Avodas HaKodesh by Rabbi Azulai, the Chida, zy"a, that a person must say every day that "I believe that everything comes from G-d, may He be blessed, whether they are things good for the body or things good for the soul. This is based upon the following Scripture, "And you should remember the L-rd your G-d, for He is the one who gives you the strength to perform valiant deeds."
