Tetzaveh #3- Urim V'tumim?

It says in shemot perek 28 pasuk 30 "וְנָתַתָּ אֶל חשֶׁן הַמִּשְׁפָּט אֶת הָאוּרִים וְאֶת הַתֻּמִּים"

What were the Urim and Tumim that are reffered to in this weeks parsha? Chabad.org says they were the two inscriptions of the Divine name. What are other opinions on what they mean and how they worked?

Tetzaveh #2- Why Bells?

In this week's Parsha, parshat tetzaveh, it talks about all the different clothing that kohanim and the kohen gadol must wear. One of the items that a kohen gadol must see is bells on the me'il. Why we're the bells attatched to the hems of the me'il?

The midrash gives many answers to this question. One is that perhaps, since the kohen gadol was so holy, upon entering the kodesh section of the mishkan the bells would ring, which was a a sign for all the angels who dwelled in the kodesh to fly away. Hashem wanted them to leave because some of these angels were angels of din, criticism, who would attempt to point out even the slightest errors of the kohen gadol. Hashem did not want such a holy man to be treated with disrespect, so He made sure that the angels would leave as soon as the kohen gadol entered. What other purposes could there be to the bells?

Tetzavah #1- Missing Moshe Rabeinu?

In this weeks Parsha, Parshat tetzave, we see that moshe's naem is never mentioned. Rabbi Chanina bar Papa understands the reason Moshe is not mentioned is because Parsha Tezevah usually falls out around the birth and death of Moshe. Moshe was born on a leap year in adar and his birth and death occurred on the same day, the first month of adar. What other reasons could this weeks parsha not have mentioned Moshe's name?

Teruma #4- More precious?

In perek 25 pusukim 3-7 the torah lists the 13 keilim that were donated to build the mishkan. A few of the keilim donated were gold, spices, red dyed ram skins, and shoham stones. Shoham stones were listed second to last which seems strange because they were one of the most important items. So why were they listed second to last? 

A Gemara in Yoma explains that since the jews worked hard to get the other materials they became more special in a way. The shoham stones were carried by a cloud and even though they have more significance to building the mikdash does not mean they were more important.

Teruma #3- For Me?

In pasuk bet it says to terumah for me "li". Why does it say "li"? Wouldn't it have been enough to say to take terumah? Rashi says "li" means dedicate for my name. 

Teruma #2- 2 Arons?

The torah commands the keilim to be built using the singular form of the verb. In Perek 25, Pasuk 10, however, Only the Aron is in the plural form According to the Kli Yakar, every Jew should of course be learning Torah all day and night. However, since this is impossible, two Jews can agree that one will learn Torah full time, and another will work to support him and earn a share of his mitzvah. The Aron Kodesh represents Torah learning, and since nobody can study Torah to the maximum capacity on their own, the action describing the building of the Aron is plural. Why else might the Aron be in the plural form?

Teruma #1- Make an Aron?

In Shemot 25:10 the pasuk states וְעָשׂ֥וּ אֲר֖וֹן עֲצֵ֣י שִׁטִּ֑ים אַמָּתַ֨יִם וָחֵ֜צִי אָרְכּ֗וֹ וְאַמָּ֤ה וָחֵ֙צִי֙ רָחְבּ֔וֹ וְאַמָּ֥ה וָחֵ֖צִי קֹמָתֽוֹ׃ 

"they shal make an ark of acacia wood, two and a half cubits long, a cubit and a half wide, and a cubit and a half high"

The introduction to the command of building the Aron differs from the commands to build the other vessels. The pasuk states "ועשו ארון”,   

“They are to construct an Ark”. Why is this commandment given in plural? Why does it say "They shal construct" rather than “You should construct”? 

According to Data Zkenim, the reason is because the Aron is so tremendously holy and therefore every Jewish person should feel like he had a part in making the construction possible.
