Hashem tells Moshe to collect pure olive oil to feed the “everlasting flame” of the menorah, which Aaron is to kindle each day.

The priestly garments, to be worn by the kohanim (priests) while serving in the Mishkan, are described. All kohanim wore:: 1) the ketonet—a full-length linen tunic; 2) michnasayim—linen breeches; 3) mitznefet or migba’at—a linen turban; 4) avnet—a long sash wound above the waist.

In addition, the kohen gadol (high priest) wore: 5) the efod—an apron-like garment; 6) the choshen—a breastplate containing twelve precious stones inscribed with the names of the twelve tribes; 7) the me’il—a cloak, with gold bells and decorative pomegranates on its hem; 8) the tzitz—a golden plate worn on the forehead, bearing the inscription of Hashem’s holy name.

Tetzaveh also includes Hashem’s  detailed instructions for the seven-day initiation of Aaron and his four sons—Nadav, Avihu, Elazar and Itamar—into the priesthood, and for the making of the golden altar, on which the ketoret (incense) was burned.

On Monday night and Tuesday, we celebrate Purim. The festival of Purim commemorates the Divinely orchestrated salvation of the Jewish people in the ancient Persian Empire from Haman’s plot “to destroy, kill and annihilate all the Jews, young and old, infants and women, in a single day.” The hero of the Purim story is Esther who told of this plot to her husband, king Achashverosh, thereby saving the Jewish people. It is celebrated with Megillah readings, gifts of food, charity, feasting, and merriment.

On Purim, it is a custom to dress up. This is to increase joy and also to symbolise how Hashem was hidden in the miracle story and it appeared natural.

Compare the story of Purim with that of our other holidays. Ever notice how the plot features no open miracles? Instead a lot of people were in the right place at the right time to provide just the political clout necessary when needed. What a coincidence. We know this was no coincidence, rather deliberately orchestrated by Hashem who stood behind the stage.

Hashem created a system for the world called nature. But there are two ways for miracles to happen. One is by overriding the system, for example splitting the sea.

But there is a second way. It is by playing with the rules and still finding a way to win. That was Purim. The aim was achieved without any natural laws being broken. This kind of miracle shows that the laws of nature are but a tool to Hashem in his running of the world. These miracles show G-d's essence, which has no name to it, hence why the Megillah does not mention Hashem’s name. 

The Gemara states that in the times of Moshiach, the Holidays will not be celebrated since the speciality of the day will be null in comparison to the light of Moshiach. The exception to this is Purim. Purim will be celebrated even during Moshiach. The reason is because Purim celebrates a miracle that occurred through natural, hidden means, which aligns with the Geulah where God's presence is revealed within the natural world.

Rabbi Dov Ber, the second rebbe of Chabad, was once on a mission from his father, Rabbi Schneur Zalman, the founder of Chabad. His travels brought him to the town of Orsha in time for the festival of Purim.

The usual crowd of merrymakers gathered in the synagogue and the cantor read the Megillah in the traditional singsong tune. After concluding a job well done, as was customary in the shuls of old, a tray was set out for people to leave tips for the reader.

Rabbi Dov Ber reached into his pocket and placed a five-ruble note in the dish. The simple folk were shocked at this enormous amount, as the entire community’s donations didn’t even add up to one ruble. The Megillah reader was so taken aback, he turned to the visitor and said, “Rebbe, I really don’t deserve such a large sum!”

Rabbi Dov Ber responded, “No, no. You deserve it alright. I heard you read a marvelous story that I’ve never heard before.”

When the venerable teacher in Lubavitch, Rabbi Shmuel Gronem Esterman, related this story to his students, he explained:

Rabbi Dov Ber heard Megillah from his father every other year of his life. And from his holy lips, Rabbi Dov Ber only heard deep, G‑dly secrets. This was indeed the first time Rabbi Dov Ber actually heard the plain Purim story read aloud.
