I know a lot of arguments against the wearing Techelet from my research etc. and I would to now hear some arguments for the Techelet. Does anyone have any arguments that support the Techelet?

    You may want to specify what you're talking about. Otherwise, I'm tempted to answer simply "Bamidbar 15:38."

    Have you looked at tekhelet.com/pub.htm ? Is there anything there in particular that you want a different answer to?

  • @issacmoses Well, it is impossible for me to wear Techelet because of what the Ben Ish Hai, Arizal, and Zohar say (see Ben Yehoyada Baba Mesia 61b). According to the Kabbala, the Techelet won't return until the Mashiah. This argument is mostly for Ashkenazim, not Sefardim. Also, because HaRav Musafi Shelita always uses the reason of "gedole hador" but sometimes I agree with people that that's not going to cut it. Because there are other Gedolim that say to wear. Whatever, I'm talking about the Petil Tekhlet specifically. Dec 25, 2011 at 15:28

One argument is from Chazal's silence regarding animal dyes. Chazal spend much time lambasting Kalei Ilan (the plant based indigo), but never once complain about a fake animal based indigo (by 'indigo' I mean a dye that is the right color and does not fade). So either there was only one animal based indigo dye and that was it, or there were others, but all were kosher at least Bedieved as Techelet. Either way, if we can prove that Chazal knew about an animal based indigo dye, it must be kosher for Techelet. As this article points out, people were using the Murex to dye BLUE (not just purple) even before the times of Chazal, based on certain archaeological findings. If so, it is kosher. And if we have it, we should wear it because God said so!

    that's a great argument I never thought of or heard of before :)

    @H'Gabriel What in the world is a Kosher Chilazon!?! Also, the Tachish was used in the Mishkan, and it wasn't kosher.

    @H'Gabriel The Shulchan Aruch does not discuss Yovel which has nothing to do with the mikdash.

    @H'Gabriel The bavli Shabbat 26a says the hunters for chilazon lived along the Mediterranean coast. At best we have a machloket. At worst we have one person writing 1000 years after the loss of techelet and one person writing while wearing techelet. Either way, the Kinneret is so small that no species could be hiding in there and we know there is no species in there that makes a blue dye. If the chilazon ever spent time in the kinneret, it certainly is not there now.

Numerous points were made here which need to be answered:

(1) Regarding the reasons we believe that the Murex trunculus is indeed the hillazon of hazal, please see my latest article: http://tekhelet.com/pdf/TekheletThreadsOfReason.pdf

(2) Regarding the Arizal's statement that after the hurban habayit tekhelet is no longer available, please see my article: http://tekhelet.com/pdf/HistoryMesorahNignaz.pdf

(3) Regarding the difference between Kela Ilan (Indigoferra tinctoria) and the Hillazon (the proposed Murex trunculus) - while the dyes today both produce the same color and are both fast to wool, in ancient times the dye processing most probably contributed to a difference in fastness; see http://tekhelet.com/pdf/testability.pdf

(4) Regarding chemicals, we use chemicals and indeed the Gemara itself says chemicals were used. For more on this, see: http://tekhelet.com/pdf/Sammanim1.pdf

(5) Regarding the Kinneret issue: Shlomo Moshe Scheinman (Solutions to Fundamental Problems Regarding Tekhelet) explains that the Kinerret is merely R. Yehuda's attempt to reconcile the fact that Zevulun, who is to be blessed with the hillazon, held that Zevulun’s territory did not get to the Mediterranean; but R. Acha in Zohar rejects this and holds that Zevulun did have Mediterranean access, so there is no need to postulate Kinneret.


Based on overwhelming physical evidence. and

1) We knew the color from the authenticated remains of קלא אילן that were found in Wadi Murabaat, and Hazal say that the two are indistinguishable.

2) The massive archaeological evidence that Baruch Sterman came up with was convincing.

3) Rabbi Moshe Tendler had said that if there are physical remains of a tradition, then one can't say the Mesorah was lost.

4) Rav Aharon Lichtenstein paskened that if you put techelet on your Tallis, you should say שהחיינו with a ברכה the first time you do so. This find confirms the truth in Rabbi Tendler's statement.

As an aside, while Rav Hershel Schachter doesn't eat Turkey because there's no Masorah on it, he does have תכלת in his tallis

    How is 4 an argument to support Techelet? It's just reporting how one person Paskined.

Normally, I would not want to give mystical oriented answers on this site, since they can be easily misunderstood, and it's a topic that normally should only be discussed in person. However, since it was implied in the comments that mystical reasons are an argument against techelet, I will explain the real reason of why I DO wear techelet.

It says that only in the times of Moshiach will Techelet be revealed again.

The story of the Murex being the correct animal has the following history.

  • The first person to propose the idea was the first chief rabbi of in 1913 Israel. However, he was unable to make the dye blue, and so did not continue further.
  • In the 1960s a piece of fabric was found with a blue dye on Masada, however this piece of fabric was unknown and hidden in bins of artifacts until 2010.
  • In the 1980s the method to make the Murex dye blue was found.

Now, in the gemora in Sanhedrin, following a long list of statements about the age of Moshiach it says the following line (98a):

"R' Abba said: There is no clearere indication o the "end" than this, as it is stated: "But you, O mountains of Israel, you shall shoot forth your branches and bear your fruit for My people Israel when they are about to come."

All the commentators say that this is the strongest proof for the times of Moshiach. The land will not produce fruit, but it will when the Jews come back to Israel.

Further (99a), Rav Shmuel says:

"There is no difference between this world and the Messianic Era except for Jewish independence from the dominion of foreign kingdoms."

(this is the opinion cited by Rambam)

Also cited in many places, is the fact that the "Times of Moshiach" will happen "bit by bit", and according to the Rambam, will happen naturally over time. Further, as cited in Daniel, and Isiah, the prophecies regarding the return of the Jewish people to Israel will become clear to those in that generation, even if they are not clearly understood in previous generations.

  • Now, in 1913, Israel was still fairly desolate. (see this picture here from 1917 of Tel Aviv)
  • In 1959, the new version of drip irrigation, which has preventive measures against dust and small particles, made it possible to use the technique in Israel, and in the 1960s, Israel started to make the "deserts bloom".
  • Then, in the 1970s and 1980s the movement to establish settlements and farms in the mountains and hills of Judea began in earnest, causing the prophecy of Isiah to be fulfilled without any doubt.
  • In 2010, the Jewish population of Israel (according to some counts), became the largest Jewish population in the world.

In other words, in accordance with the words of the Kabbalists, Techelet has returned to the Jewish people in the times of Moshiach, as defined by R Abba. (with no dissenting opinion recorded in the Messora)

All of the above (Except for the history and timeline, that is my own personal observations) is inspired by and parts taken from the sefer "Torat Eretz Yisrael" by Harav David Samson, based on the statements of Harav Tzvi Yehuda HaCohen Kook. If any of this isn't clear, I suggest reading that book where many many more sources are brought down to explain these ideas.

  • I'm sorry, no offense to you, but I think R' Yaakov Moshe Hilel Shelita knows this Gemara and every "kabbalistic proof" you can bring, but he still holds of that B"Y in B"M 61b. Dec 25, 2011 at 18:49
  • I want to write a Teshuva on this matter and I can't find any proof except "safek deorayta". I don't want to look like a fool by writing a Teshuva and not disproving ALL supporting reasons. I'm not dismissing you or Mossad HaRav Kook (I love their publications BTW) I am just taking Rav Yaakov Hilel OVER the rest. Dec 25, 2011 at 19:02
  • @H'Gabriel you clearly did not even bother to read my answer.

  • Does Rav Yaakov Hillel discuss the timeline of Techelet along with the timeline of the how Israel made the desert bloom?

  • I did, but I'm not looking for a counter to my answer of the Kabala, I'm looking for actual scientific/rabbinic proof. I'm not looking for someone to try and disprove my answer, just the other side. Dec 25, 2011 at 19:04
