Who knows three hundred forty six?

ששה וארבעים ושלוש מאות - מי יודע?‏

The traditional Passover song "Echad - mi yodeya" implies a possible presupposition that there is a Jewish significance to be found for each natural number. Accordingly, there is an ongoing series on Mi Yodeya that is attempting to unearth significant Judaism facts about each number, in sequence.

What significant Judaism facts are there about the number 346? The more significant within Judaism and the more intrinsically dependent on the value 346, the stronger the answer. Please include sources for your information wherever possible, as with all other answers on this site.

Together, we we shall build for Hashem my G-d a list of numbers on this mi-yodeya series the likes of which the world has never seen since the days of Elisha. Please refrain from lazy gematrias.

  • I thought only Isaac Moses was in charge of this. Did you take over for him?

    @DanF I thought that since there hasn't been one since April, that it was time that we moved on with this. Jan 10, 2018 at 19:20
  • I don't think that's any problem. It's been a while since I last viewed one of these numerical questions. I don't recall if Isaac had awarded "bounty" points for the best answer.

    @DanF אלישה is one of the nations mentioned in Genesis, and this seems to be the spelling that works

Once every 28 years we make a special Bracha when the sun returns to its original location. 28 Jewish years will generally have 346 months. Every 19 years has 7 additional months and the 9 additional years will generally have 3 additional months.

19 x 12 = 228 + 7 = 235

9 x 12 = 108 + 3 = 111

235 + 111 = 346 months

  • But we don't make it on the same day every 28 years (on the Jewish calendar) so there could be more or fewer complete months

  • In general it will work out to 346 Jewish months. Jan 11, 2018 at 0:08

    More accurately, 28 years are 28*365.25=10227 days. Averaging at 29.5 days per lunar month, there are 10227/29.5=346.67 months in a Machzor Gadol.

  • FYI, there is an intersting web site published by Remy Landau (Google his name, you should be able to find it) that explains why we wish people who celebrate their birthday *You should live for 120 LONG years." The article explains how the year you're born can possibly add up to about extra month in your 120-year life.

In Israel, a normal year (Non-leap year / kesdira) has 346 days that are not a Yom Tov. The math details:

A normal kesidra year has 354 days

  • 2 days Pesach
  • 1 day Shavuot
  • 2 days Rosh Hashanna
  • 1 day Yom Kippur
  • 1 day Succot
  • 1 day Shmini Atzeret

8 days total; 354 - 8 = 346.

  • @DoubleAA Of course it is! Is my question unclear by specifically stating not a "Yom Tov"? I mean, I know that Shabbat is a mo'ed.

  • You defined a Yom Tov as a day off here work is forbidden

    Jan 11, 2018 at 15:47
  • @DoubleAA I guess something isn't clear. I was narrowing my question to specifically Yom Tov which Shabbat is not. However, my thinking was that some people may think of all 8 days of Pesach as "Yom Tov", I said "days when work is forbidden" and followed that by stating excluding Hol Hamo'ed. I thought that clarified all the criteria.

  • "days when work is forbidden" includes Shabbat, Yom Tov, and Chol HaMoed. Work is forbidden on all of those.

Days in a normal year (כסדרה) one is allowed to eat חמץ (chutz l'aretz). Full days (including Erev Pesach) in a normal year (כסדרה) one is allowed to eat חמץ (Eretz Yisroel).


The Gemara in Menachos 43: says that King David was in the bathhouse and when he took off his Tzitzis he was disappointed that he was naked from Mitzvos. When he remembered that he has a Bris he was happy.

Maharach Ohr Zarua Chapter 11 mentioning this story of King David says that Milah is a Mitzva at every moment.

Based on this a child that is born in a year that has 353 days will have the Mitzva of Bris for 346 days in the first year of his life.


Three hundred and forty six (346) is represented in Hebrew as שמ״ו, which is literally His name.

Like with all names, they are not the actual being and essence (מהות ועצמות) of the one represented by the name. Yet, the name is intrinsically bound to that essence. In the language of Chassidut, Name is only intended as a kind of handle for another and that handle is the means for the other to grasp and to connect to the Essence associated with that name.

In traditional Torah related abbreviations, 346 (שמ״ו) is the abbreviation for Heavens and Earth (שמים וארץ).

And it is in this context that 346 teaches us many important principles in the Torah.

Bereshit 14:19

וַיְבָרְכֵהוּ וַיֹּאמַר בָּרוּךְ אַבְרָם לְאֵל עֶלְיוֹן קֹנֵה שָׁמַיִם וָאָרֶץ׃

We learn that the blessing of Malkitzedek, who was King of Shalem and Priest to G-d above, was that Avram was blessed to G-d above, owner of Heaven and Earth.

And this follows the teaching found in Mishlei 3:19

יְהוָה בְּחָכְמָה יָסַד־אָרֶץ כּוֹנֵן שָׁמַיִם בִּתְבוּנָה׃

That G-d founded the Earth with wisdom and established the Heavens with understanding. And through this process, they became His possession, like Rashi teaches.

And just as the blessings of Avram came from the Owner of Heaven and Earth, so too, this is the source of our blessings as found in Tehillim 115:15

בְּרוּכִים אַתֶּם לַיהוָה עֹשֵׂה שָׁמַיִם וָאָרֶץ׃

In addition to this referring to the One who blesses us, it also reminds us that G-d is the one who helps us, both individually, like in Tehillim 121:2,

עֶזְרִי מֵעִם יְהוָה עֹשֵׂה שָׁמַיִם וָאָרֶץ׃

and collectively, like in Tehillim 124:8.

עֶזְרֵנוּ בְּשֵׁם יְהוָה עֹשֵׂה שָׁמַיִם וָאָרֶץ׃

And it is taught from Midrash Mishlei 31:5 that if we are engaged in Torah day and night, G-d counts it for us as if we are partners with Him in maintaining Heaven and Earth.

אמר הקב"ה לישראל: בניי, היו מתעסקים בתורה ביום ובלילה, ומעלה אני עליכם כאילו אתם מעמידין שמים וארץ, שנאמר (יהושע א ח): "לא ימוש ספר התורה הזה מפיך והגית בו יומם ולילה"

And this same sentiment is repeated by the prophet Jeremiah 33:25.

כֹּה אָמַר יְהוָה אִם־לֹא בְרִיתִי יוֹמָם וָלָיְלָה חֻקּוֹת שָׁמַיִם וָאָרֶץ לֹא־שָׂמְתִּי׃

And 346, through this phrase Heavens and Earth, also reminds us of the final redemption like is referenced in Tehillim 134:3

יְבָרֶכְךָ֣ יְ֭הוָה מִצִּיּ֑וֹן עֹ֝שֵׂ֗ה שָׁמַ֥יִם וָאָֽרֶץ׃

And it also teaches us about the World to Come like in Isaiah 65:17.

כִּי־הִנְנִי בוֹרֵא שָׁמַיִם חֲדָשִׁים וָאָרֶץ חֲדָשָׁה וְלֹא תִזָּכַרְנָה הָרִאשֹׁנוֹת וְלֹא תַעֲלֶינָה עַל־לֵב׃

And all of this is directed toward the unification of Heaven and Earth to reveal His Oneness like is expressed by Ramban to Shemot 20:13:1.

שתי לוחות כנגד שמים וארץ וכנגד חתן וכלה וכנגד שני שושבינין וכנגד שני עולמים. וכל זה רמז אחד, והמשכיל יבין הסוד:

That just as the two tablets of the law are one, so too, Heaven and Earth are one, Bridegroom and Bride are one, Moshe and Aharon (the two Escorts) are one and this world and the World to Come are one.

And this sentiment is what was expressed by Zecharia 14:9.

וְהָיָ֧ה יְהוָ֛ה לְמֶ֖לֶךְ עַל־כָּל־הָאָ֑רֶץ בַּיּ֣וֹם הַה֗וּא יִהְיֶ֧ה יְהוָ֛ה אֶחָ֖ד וּשְׁמ֥וֹ אֶחָֽד׃

And the L-rd shall be king over all the earth; in that day the L-rd will be one and His name (שמ״ו) one.

  • @DonielF There is no mention of gematria in my answer whatsoever. However, it should be noted that the last paragraph in the question, which you are referencing, was not in the original question. It was added by someone else after an answer had been provided. According to site guidelines, modifying questions after answers have been provided is prohibited. Jan 10, 2018 at 23:28

    Gematria is always forbidden by this sequence of questions. And your first line is “346 is represented in Hebrew as שמו, which is literally His name.” That’s just a fancy way of saying that the gematria of שמו is 346.
