Elevation of the Kohen on the Mount of Olives

The Kohen standing on the Mount of Olives had to be able to see the entrance of the Sanctuary as he sprinkled the blood of the Red Cow. The Gemara explains that to do so he would need to look over the eastern gate of the Temple Mount, because if he looked through that gate the elevations of the Temple were such that he could not see the Sanctuary entrance. It can be shown, however, that there is a very simple way to see the Sanctuary entrance by looking through the gate.

Locating the Courtyard Upon the Temple Mount

Even though Tractate Middos does contain a lot of detailed measurements for the Second Temple, one of the places where the Tanna is vague is when he describes the location of the Courtyard upon the Temple Mount. The Mishnah does not give explicit numbers but rather states that the southern area (that is, the area between the southern Temple Mount wall and the Courtyard) was larger than the eastern area, and the eastern area was larger than the northern area, and the smallest area was in the west. I looked for a simple mathematical way to calculate the range of possible locations where the Courtyard could have been placed, but I didn't find one.

Chanukas HaLEGO® Mizbeach

When the Chashmonaim recaptured the Temple many years ago, they were horrified to discover that the Altar had been used for pagan worship. As a result, they disassembled the entire Altar and ramp and built them anew. Through a similar siyata dishmaya (although on a smaller scale - literally and figuratively) I was able to refurbish and add to my LEGO® model of the Altar just in time for Chanukah.

The Nivreshes as an Indicator of Zman Kriyas Shema

How did a golden candelabra mounted on top of the Sanctuary Building let the people of Jerusalem know that it was time to recite the morning Shema?

Thickness of the Courtyard Walls

Nowhere in tractate Middos does the Mishnah mention the thickness of the walls surrounding the Temple Mount or the Courtyard, yet some suggest that this measurement is hinted to in the Torah itself.

Wall Thickness of the Chambers of the Knives — בית החליפות


SUMMARY Using the standard Talmudic ratios of wall thickness to height it is possible to calculate a minimum wall thickness for the Chambers of the Knives.

Other Options for Old Knives in the Temple

When Temple property becomes unfit for use there are a number of things which could be done with it. The treasurers could repair the item and put it back in service, recycle the item and use it for some other sacred purpose, or redeem the item by selling it and returning the profits to the Temple treasury. I would like to examine whether any of these options applied to old slaughtering knives of the Kohanim.
