Yoma 21b – 23b: The Ramp of the Mizbeyach

As recorded in the Torah, it is forbidden to access the Mizbeyach with steps. For this reason, a large ramp was built on the southern side of the Mizbeyach which measured 32 amos long, 16 amos wide, and 9 amos tall. While all ramps in the Beis Hamikdash conformed to a ratio of 3 amos in length for every amah of height, the slope of the Mizbeyach ramp was slightly shallower, with a ratio of 3½ amos + 1⅓ fingerbreadths of length for every amah of height.

Yoma 19a – 21a: The Chamber of Melach

Starting in the southeast corner of the Azarah were three chambers which took up the entire 11-amah length of the Ezras Yisrael and continued into the Ezras Kohanim.

  The first of these was the Chamber of Melach which held a large supply of salt used for

Yoma 16b – 18b: The Beis Hamoked

Built around the first of the major gates on the northern side of the Azarah was a large complex with a domed ceiling called the Beis Hamoked [Hall of the Fire]. This building served as sleeping quarters for the watch of Kohanim currently on duty as well as a place for them to

Yoma 14a – 16a: The Chambers of the Oils and Metzoraim

The chamber in the southwestern corner of the Ezras Nashim was called the Chamber of the Shemanim [Oils] and served as the storage area for the Beis Hamikdash’s supply of oil, wine, and flour. It was named for the oils stored here since

Happy Chol Hamoed Succos 5784!

On the holiday of Succos, the Rejoicing of the Water-drawing would take place inside the Women's Courtyard. The celebration began on the second night of the holiday when the great sages and pious men of the generation would assemble in this courtyard to dance, juggle, and sing God's praises while scores of Leviim stood upon the fifteen round steps in front of the Nikanor Gate (in the western wall of this courtyard) providing musical accompaniment.

Yoma 11b – 13b: Binyamin Hatzaddik and the Yesod of the Mizbeyach

 It was vitally important that the Mizbeyach be built in precisely the right location and so a prophet was consulted to pinpoint its exact coordinates. In addition, although the entire expanse of Har Habayis was built over a system of arches to protect it from

Yoma 9a – 11a: The Nikanor Gate

The Nikanor Gate was one of seven major gates in the walls surrounding the Azarah. All of these major gates measured ten amos wide and twenty amos tall and had double doors. When the Jews returned from exile to build the Second Beis Hamikdash they were poor and could not afford to spend lavishly on the structure. At some later point when their financial situation had improved they were able to plate all of the doors of the Beis Hamikdash gates with gold. The only exception was the

Animals on Erev Pesach

The Gemara (Pesachim 65b) states that on erev Pesach the Kohanim were walking around on the floor of the Beis Hamikdash up to their ankles in the blood of the festival offerings. How many animals would it take to produce that much blood?

The Terry Elan Memorial Lecture 2023: House of Shadow and Light

To mark my father's yahrtzeit on 29 Shevat I delivered a new slideshow titled House of Shadow and Light. This shiur explores the relationship between the path of the sun and the structure of the Beis Hamikdash. The slideshow covers some topics from earlier blog posts, some ideas discussed in my book, as well as some brand new material.

The video now has closed captions thanks to the efforts of Martha Goodman and the Disability and Inclusion Services, Macks Center for Jewish Connections in Baltimore, MD.

Happy Isru Chag Succos 5783!

At the end of another Succos in the Beis Hamikdash the Kohanim and Leviim started cleaning up after yom tov. They had more than just their succos to take down — there was also a large project waiting for them in the Women's Courtyard.

Model Ma'arachah on Display

When visitors to the Ner Yisroel neighborhood now walk by the site of the yeshivah's annual Lag Ba'omer bonfire, they will see more than just scattered wood and charred logs. Some volunteers used a little imagination and a lot of hard work to transform those "spent firebrands" into a hands-on learning experience.

Behind the Scenes: Beis Hamoked Basement

I am in the process of importing my 3D model of the Beis Hamikdash into the Unity game engine. Although many of the models that were used to create the images for my book already exist, the app is going to allow the user to explore the entire Beis Hamikdash and so many more areas have to be created. Here is a sneak peek at one of those new scenes.

Here is another 4x4 micro diorama for Pesach whose full scale physical counterpart will, sadly, have to wait until next year.
