Keys of the Past, Keys to the Future Ancient Keys and their Role in the Operation of the Beis Hamikdash


The events surrounding the destruction of the Beis Hamikdash are recorded in various historical sources and religious texts, and many of these have found their way into the current liturgy of Tisha B’Av. Although sometimes garbed in poetry and metaphor, the elements being described are real objects of stone, metal, and wood, and by further examining their details, we can gain a better understanding of our prayers. Consider the following incident, referenced in Kinnah 32, that occurred during the final hours of the First Beis Hamikdash era:

Many groups of young Kohanim gathered together, with the keys to the Heychal in their hands. They ascended to the roof of the Heychal and called out, “Master of the World! Since we have not merited to be faithful treasurers, the keys shall be transferred back to You!” They threw the keys heavenward and the form of a hand appeared and took the keys from them. The Kohanim then threw themselves from the roof into the burning remnants of the Temple below (Taanis 29a).

The Heychal, or Sanctuary Building, had a large entrance on its eastern side, but this entrance had no doors and thus needed no keys. The inner part of the building (the Kodesh) did have an entrance that was blocked off by two sets of doors, but these doors – which were locked each night – were opened without the use of keys. So which keys were these groups of Kohanim holding? And why do the Kohanim refer to themselves as “treasurers”? Let’s take a closer look at the keys of the Heychal.

The Heychal was the largest structure in the entire Beis Hamikdash. It measured 100 amos (about 150 feet) tall and was given a gleaming coat of white plaster so that from afar it appeared, in the words of Josephus, “like a mountain clad in snow” (see diagram). (Although the incident in the Gemara above happened during the times of the First Beis Hamikdash, the description given here is based on what we know of the Second Beis Hamikdash, which was similar but not identical.) The large hall, or Ulam, on the eastern side of the building had an entrance that measured 20 amos wide and 40 amos tall (30x60 feet). There were no doors in this entrance; rather, it was blocked off by a large, and magnificently woven, curtain.

Centered in the Ulam’s western wall was a gateway leading into the Kodesh (Holy). This gateway measured 10 amos wide and 20 amos tall (15x30 feet) and had two sets of doors. One set of doors was affixed near the eastern side of the gate, and another set of doors was affixed at the western side (see diagram). These doors were secured from within (i.e., on their western side) using two different methods: bars of wood or metal that slid into place and held the doors closed, and some sort of pins (or other manually-operated locking mechanisms) that prevented the doors from being pushed open.

Now, if the doors were locked from inside the Kodesh, how did the Kohanim open them? Within the Ulam, to the north and south of the gateway to the Kodesh, were small passageways in the Ulam’s western wall (see diagram). These led into a series of interconnected rooms, called tauim, that were built all around the outside of the Heychal. The Kohen charged with opening the Heychal doors would approach the northern passageway and unlock the door located there with a key. After walking west into the first tau, he then turned to the south where another passageway led into the Kodesh. After unlocking the door of this second passageway with a different key, he entered the Kodesh and approached the two doors at the western side of the Heychal gateway. The Kohen removed the locking bars and pins and then swung the massive doors inward to open them. Then he repeated this procedure to open the two doors at the eastern side of the gateway.

The Mishnah in Keilim (14:8) discusses the halachic status (with regard to tumah contraction) of various types of keys. One of the keys described there is the “arkuvah” key, so called because its shaft was bent at different angles that resembled an arkuvah, or knee, of a person (see diagram). It is quite possible that this same type of key was used to unlock the doors of the Heychal.

Thus far, we have accounted for a total of two keys, yet the Gemara’s account speaks of groups of Kohanim, each holding keys, implying that there were many more than just two. The missing keys may be those of the tauim. Thirteen tauim are shown in the diagram, but there was another level of rooms just below these and another level just above them, for a total of 38 tauim, all of which were interconnected and separated by doors. Without working out the specifics of which of these doors had keyed locks, and taking a rather conservative stance that there was one only key per tau, this results in 38 keys. If each group of Kohanim in the Gemara’s story was holding one key, this would certainly be enough to qualify as “many” keys. This approach would also explain why they refer to themselves as “treasurers” since the tauim were used to store the Temple’s gold and silver.

Tisha B’Av brings the memory of the Beis Hamikdash into sharper focus, but recalling and retelling the details of its structure has even more of an impact than we might realize. Hashem encouraged the prophet Yechezkel as follows: “Just because My children are in exile, shall the building of My House be abandoned? I consider its study as equivalent to its actual construction. Go tell the people to involve themselves in the study of the structure and, as a reward for their study of it, I will consider it as if they are involved in its actual construction!” (Tanchuma Tzav §14).

May we all merit to see the building of the Third Beis Hamikdash speedily in our days.
