This past Shabbat, someone in my shul showed me a difference in spelling of the first word in the middle prayer of Shabbat Musaph.

Most Nusach Ashkenaz and Sephard spell it as תכנת שבת (Loose translation - "You planned the Shabbat..")

Nusach Ar"i (Chaba"d) spells it as תקנת שבת (loose translation - "You repaired the Shabbat" (or established Shabbat as a "reparation")

I may not have made the best English translation of either version, so please edit and / or comment.

There is an obvious difference in meaning, although, the pronunciation (for most) is identical. Why is there this difference in meaning? What concepts are being conveyed with each one?

The version used by the Alter Rebbe in his siddur, which is not strictly the nusach of the Ari z"l, but rather according to the nusach of the Ari z"l, is based upon a comment found in the siddur of Rabbi Shabtai of Rashkov. Rabbi Shabtai was the recognized expert in the nusach of the Ari z"l from the time of the Ba'al Shem Tov and served as his Sofer.

In Rabbi Shabtai's siddur for Musaf of Shabbat, it writes as the primary version that it is תקנת שבת. But it points out that there is an alternate version of תכנת שבת.

The first version would be using a language that is also attributed to Eliyahu HaNavi from Patach Eliyahu in the Zohar. It has a connotation of both fixing, like repairing or adding something that is missing, and also a beautification, like in jewelry or ornament.

The second version means to establish, like Midrash Konen (ספר מדרש כונן נמצא בילקוט הרועים הגדול ) is a midrash on the creation of the universe.

It's worth pointing out that although the recently published Siddur for Shabbat of Rabbi Moshe Chaim Luzzato by Machon Ramchal prints the text of the siddur as תכנת שבת. It quotes the Ramchal himself writing in Kitzur HaKavanot (authoritative text written by Ramchal) that the text is תקנת שבת. The Ramchal has specific kavanot associated with this version of the text. The tradition is that Ramchal teaches the Nimshal to the Ari's z"l Mushal. By many, including the Vilna Gaon, he is considered the authority.

Another source that is purported to be by an expert of the Ari z"l is the siddur of Rabbi Shalom Sharabi, who originated from Yemen passed through India and ultimately ended up in Israel. In his siddur for Musaf of Shabbat, he follows the version תכנת שבת, but offers no explanation.

The source for these two versions seems to be based upon a possible typographical error.

The first (תקנת שבת) is the version written according to the siddur of Rav Amram Gaon according to the Mossad HaRav Kook edition, page 78:33.

The second version is attributed to Rav Amram Gaon and Rav Sa'adiah Gaon by the Avudraham in discussing the proper text of Tefillat Musaf for Shabbat. Avudraham follows the nusach used by the Baladi Jews of Yemen which is completely different but says that Rav Amram Gaon used the version תכנת שבת. He emphasizes that it is not his minhag to say these opening words and therefore will not offer an explanation to their meaning.

  • Should be emphasized that the Siddur R. Amram retained different versions; as you can see from this edition and this one (as noted in the latter by Frumkin, the publisher). Additionally, contrary to what you write, the authoritative ed. of R. Saadia's siddur (eds. Assaf, Joel, Davidson) has תקנת and not תכנת.

  • @Oliver I said nothing about Rav Saadia Gaon’s siddur as you say. To the contrary, I suggested that the statement from Avudraham may have been the consequence of a typo. The Alter Rebbe relied many times on what he found from the Gaonim as the guide for his decisions in the siddur. Together with the views of Rabbi Shabtai and Ramchal, which I am sure he was familiar with and the support attributed to Eliyahu HaNavi, personally, I would be inclined to think תקנת is likely the authentic version.

  • Apologies; "contrary to what you write from Abudraham...".
