Tazria/Metzora- Meeting place?

In Parshat Tazria, in Perek Daled פסוק ה׳, it is written: "אל אהל מועד", or "to the tent of meeting". What is so special about this meeting place? Rashi says it is the Mishkan, which had a very holy connection with Hashem. What else could be the place that they were going to meet at? 

Tzav #3- Avoiding Embarrassment

"במקום אשר תשחט העלה תשחט החטאת"
“In the place where the burnt-offering is slaughtered shall the sin-offering be slaughtered.” (6:18

In this weeks parsha we are told how to give certain korbanot. It is commanded that the two korbanot are shechted at the same place. What is the significance of the requirement to shecht them in the same place? Chabad.org says the reason for this is because while one korban is brought for forgiveness from a sin and another is brought as a contribution to the beit hamikdash, the reason for the korbanot being shechted in the same location is to avoid embarassment from outsiders watching the shchitah. No one will know whether the shechita is being preformed for redemption or contribution. 

What are other examples of avoiding embarrassment as seen in this weeks parsha? 

Tzav #2- Where was Aharon?

 In  the beginning of the parshah it says, that Hashem  commanded "Aharon and his Sons" when in VaYikrah only Aharon's sons are commanded. Why is this time different? According to the Tosfot HaRash , in VaYikra, Hashem does not command Aharon because He was angry about Aharon's involvement in the eigel. Now Aharon is mentioned because Moshe argued that despite Aharon's mistake he deserves honor because of his righteous offspring. Therefor, Aharon was included. Why else was Aharon mentioned in Tzav when he wasn't mentioned in other places.

Tzav #1- Bringing Bread?

In Parshat Tzav, 7:12 it says the following: יבאִם עַל תּוֹדָה יַקְרִיבֶנּוּ וְהִקְרִיב | עַל זֶבַח הַתּוֹדָה חַלּוֹת מַצּוֹת בְּלוּלֹת בַּשֶּׁמֶן וּרְקִיקֵי מַצּוֹת מְשֻׁחִים בַּשָּׁמֶן וְסֹלֶת מֻרְבֶּכֶת חַלֹּת בְּלוּלֹת בַּשָּׁמֶן: Translation: if he is bringing it as a thanksgiving offering, he shall offer, along with the thanksgiving offering unleavened loaves mixed with oil, unleavened wafers anointed with oil, and scalded flour mixed with oil. Q: Why for the thanksgiving offering, besides bringing an animal sacrifice, the donor must also bring four types of bread, and ten breads of each type, totaling forty loaves? The Netziv answers this by saying that the thanksgiving offering must be accompanied by a public celebration with many guests invited. Therefore, unlike the ordinary shelamim, the numerous loaves of bread are prescribed so that all the guests can partake of the meal. What are other reasons why the thanksgiving offering requires four types of bread? 

Vayikra #3- "Vayikra"

In passaic א perek א & ב Hashem tells Moshe to tell the jews that they have to bring karbanot to Hashem. Why does the torah decide to use the word ויקרא and not one of the other synonyms such as "וידבר"? Rashi explains that a word such a ויקרא is a word used to show affection. As extra credit one time I learned that the first Rashi of every sefer shows affection and love towards the jews. I think this is a very nice idea that the torah decides to start each sefer off on the right foot. 
Why else does the torah decide to use the word ויקרא and not one of the other synonyms such as "וידבר"? 

Vayikra #2- Why "Adam"?

In perek 1, pasuk 2, it says “בדַּבֵּר אֶל בְּנֵי יִשְׂרָאֵל וְאָמַרְתָּ אֲלֵהֶם אָדָם כִּי יַקְרִיב מִכֶּם קָרְבָּןלַיהֹוָה מִן הַבְּהֵמָה מִן הַבָּקָר וּמִן הַצֹּאן תַּקְרִיבוּ אֶת קָרְבַּנְכֶם:

“ 

Why does it specifically say אָדָם in the pasuk, as opposed to another word that means man?

Rashi says that it is referring to Adam Harishon who never gave korbanot from stolen property, since everything in the world was his. We learn from this that you can’t give korbanot from stolen property and you need to honestly acquire what you give as a korban to Hashem.

Why else would it say אָדָם in the pasuk? What is אָדָם referring to?

Vayikra #1- Blood and Fats?

In this weeks parsha, Vaykira it talks about korbanot. In the pasuk it says "וזרקו את הדם על המזבח סביב...ואת הפדר"

“They shall throw the blood on the altar all around... and the fats.” (1:5,8) But why would the blood and the fats be offered?  Chabad.org says Blood represents excitement like how we should feel toward mitzvot. On the other hand, fat represents laziness how we should be “lazy” or turn away from doing wrong things. Placing these remind us how we should act every day.
