A beautiful fabric was uncovered buried in the tomb of a Scythian warrior prince. The cloth is dated to the 5th century BCE and offers insights into life in the time of the Bible. It also had great significance for the study of tekhelet and may be the oldest surviving blue wool in existence.
Tekhelet - Fundamental Argument in favor of Murex trunculus
Просмотров 1,9 тыс.13 лет назад
Baruch Sterman discusses the key argument in favor of Murex trunculus as a "kosher" source for tekhelet in tzitzit. He brings three halachic sources and three recent archeological finds that, taken together, build a very strong case for the position that the chilazon - the marine source of the ancient authentic tekhelet - is the trunculus snail.

We know that blue dye was very expensive in Biblical times and the Torah states the nations of the world traded it as a commodity. There are records in multiple different ancient nations that show the blue dye back then was created from snails: 1. The Greek historian Herodotus (c. 484-425 BCE) mentioned that the Phoenicians produced a highly prized purple dye from sea snails, which may have also yielded a blue dye. 2. The Roman naturalist Pliny the Elder (c. 23-79 CE) described the production of Tyrian purple dye from snails, which could turn blue after exposure to sunlight. 3. The Roman writer Vitruvius (c. 80-70 BCE - c. 15 BCE) also mentioned the use of sea snails for producing a blue dye in his treatise on architecture, "De Architectura." 4. Archaeological evidence from a 3,600-year-old workshop on the Greek island of Aegina confirms that the ancient Greeks and Romans produced blue dye from snails. 5. The Greek poet Oppian (2nd century CE) wrote a poem about fishing and described a mollusk that produced a blue dye. Rashi says that the Chilazone was a chomet and he says in another place that a chomet is a snail. Then we have the archeology that shows in Israel stockpiles of murex trunculous shells with holes in the shells where people who created dyes would puncture the shells. This does not prove 100% that the murex trunculous is the chilazon but it is definitely strong evidence of it... so much so Rabbi Belski held it was vadai the correct creature.

So butchering and slicing the poor little snail just so the royalty of old could have their fancy colored robes! (It took THOUSANDS for ONE robe!) How nice….. Rotten humans!
Well said 🐌😢
Tyrian purple
I personally think the opinion of the Radzinger rebbe and the ptil tekhelet institute are both valid. The only thing that makes it Pasul if it’s made from kala Ilan
And what about the Gaon Harav Herzog who disagreed? Also it’s a machlokes the Rambam and Rashi which has never been resolved!
@@nathelondon3719 I tend to follow the Halachic opinion of the rambam. Personally it makes more sense to me
The Rabbi made a tremendous mistake. Korach made his tzitzis COMPLETELY techeiles, all the strings and the beged (Targum Yerushalmi)
No Korach’s challenge to Moshe was, “if I have a 4 cornered garment that is the color techelet, would one be obligated to add Tzitzit”
@@adollarandSense Before you say "NO" look up the Targum Yerushalmi (known as the Targum Yonason) that I cited.
Very good Shiur but how can anyone talk about Rabba Bar Chona in such a way?

Better no talis than one without תכלת!!!! Do me a favor...
I need to use more of these dyes, feed the poor and the needy is our duty. Beer to those who are using the dye to do leukemia research!!!
Your comparison of techeles to the timing lulav is false. Your are comparing a safek in the item to a safek in time. Compare a safek estrog to safek techeles. Furthermore the gemora in menochos says that if it isn't techeles then it PASSELS the mitzva of tzitzit whereas all white is definitely a mitzva.
@Nosson Rossman none at all. That’s what YOU did! There are two types of safek. A safek in Halacha and a safek in metzuiyut. There is also a chesron yediah which is NOT a safek! Perhaps you try learning the gemoras before you argue with me!
@Nosson Rossman sorry. I should have mentioned that’s he’s my Rov and asked to send you his reply.
@@NathanL613 according to the Rambam there is NO safek until you have a vaddai. That is two chatichot. Have you learnt Keritot with the rishonim before you write?
That which mzk1 below writes about the Gaon, Reb Menachem Ziembe is a TOTAL FALSEHOOD. he was misinformed or made a mistake but my Rebbe, the Gaon Rav Simche Bunim Lieberman zatzal was by Rav Ziembe every Friday night in the Warsaw Ghetto and knew his opinion. Rav Lieberman survived the camps and broke a 50 year silence to fly to a conference in Vienna (!) to publicly deny that Rav Ziemba was for the uprising.
Todah Baruch, this is a beautiful and amazing fullfilment, My family and I are greatful for you and your team, great work Achi.

I favour the cuttlefish as the source of tekhelets
Who would cover themselves in abominations? Leviticus 11:43
Amazing. Another observation ( probably halachicly irrelevant) but in ALL of human history untill about 1600ce there were TWO materials capable of creating a durable color fast blue dye. Murex, and indigo (kaleh Ilan). ( There were only 3 more materials capable of creating a blue pigment). Blue- the rarest color occurring in nature.
This is incorrect, because indigo is known even from Rabbinic literature to be an non-fast dye, while Isatis Tinctoria (woad) was another source for colorfast blue-violet, if dyed properly. If indigo fits the bill for you, you also have to accept woad, black beans and at least one kind of spirulina that are all known as natural sources for blue-violet dyes.
wow, leukemia
I have both tekhelet from the cuttlefish and sea snail
Why would God use an unclean animal such as a snail to make something he deem holy Hebrews weren't allowed to touch anything unclean
Bees are also considered "unclean," but honey is obtained from them.
@Ted Stout How is your claim convincing? "The rabbis approved of it, so it must be pure?" Sorry, as a Scriptural Jew I am not convinced.
Many Orthodox Jews, not to mention the majority, prefer not to follow the Torah's order about the "pesil techeiles" because they say they do not know the exact shade of blue or how to obtain the color. That reasoning always seemed stupid to me. By not putting the blue thread, they are breaking an express order of the Torah, while putting the blue thread, although it is not the same blue tone used by Moses, at least they show God that they are trying to comply with the precept.
There was never a single blue tone. Every batch of cords or fabric dyed with Tekhelet comes out with a slightly different shade at least. This depends also on the material. Woad has been proved to be the authentic source of this dye, but this will not faze the Orthodox Jews, who are trapped with the Rabbinic decree, recorded in the Tosefta, that the source must be the elusive Ḥilazon.
The snail is unclean as a food source.
So is the bee. Yet honey is clean.
This Purple dye was a precious dye farmed in the Mediterranean for imperial and high religious use
Techeiles can be bought in Brooklyn at Mercaz Hatecheiles 1347 404 8061 Mercazhatecheiles@@t
I really wanted to see to this done, after reading about tyrian purple, but Im saddened at how it was done. From what Ive read, its possible to extract the dye without killing the animal. Its used as a defense mechanism so all they really had to do was poke the snail until it squirted, rather than hammering its home and slicing off its organ.
There are many species of Murex - all secrete the precursors to the purple dyes. In the Mediterranean, the three species that are found - and that were used in the ancient Western world - all store those molecules in a gland that can only be accessed by breaking open the snails' shell. This is well documented by the Roman naturalists as well as by the Talmud. You may be referring to a species of Murex that is found along the Pacific coast of Mexico and down as far as Costa Rica, the Plicopurpura pansa. These were used in ancient times - and still today by the Mixtec - to dye yarn, and those snails do in fact secrete the yellow liquid when perturbed that turns into the purple dye. Whether those snails would be viable - ritually, economically, and practically - for use in making Tekhelet is an area of research that would be extremely worthwhile.
@@baruchsterman Kind of like how kosher slaughter is said by Talmud to be humane and painless.
@@thecuriousspectator2429 perhaps the original idea was that it was to be less painful, but that might not be the case anymore. Ideally they should put them down with opiates
@@baruchsterman ritually does this purple dye have any importance?
@@jakemcnamee9417 Then the meat would be drugged, wouldn't it?
Thanks for the video. I was looking desperately for a video to show me how it was done.

Pupure Schneck, haha. It's Purpur-SchneckE.
About 10 months ago I was working with a paper model and got 19 stitches from an x-acto knife when I wasn't paying enough attention to what I was doing. This video made me nervous.
Brilliant! And to make a long story short; if you can fulfill a mitzvah then you should and there is no downside. It is almost a universal opinion now that we should see the Tekhelet and remember and be reminded of the Yam of Nisim and ultimately, the Kisai Hakavod. Making Tzizit without Techelet when we have it is doing a partial mitzvah only...Or don't wear tzitzit at all!
Rubbish. The Gemara says that if it isn’t tech else then it nullifies the mitzva. Do you think that you know better than Reb Chayim Kanievsky zatzal and the Brisker rov?
Baruch ok so my name is Kathy G. Leyva. My last name should tell you something. Yes I'm sephardic and ironically my family is from Mexico so guess what we do it better. We ended up with the Mixtec tribe and only Ya knows were we get the process from because we don't kill it!!!! You don't kill the snail there is no need to we milk it! If you want more info or you want to go to Mexico (btw) I live in Chicago just had a big museum opening. So e-mail me at Katgo1@comcast.net. I'll send you some links and your welcome to go with me to Mexico. I'll house you no problem maybe I can to Israel and go basket some snails:) Kathy Leyva
Thank you for teaching me about this Dr. Sterman. I find this subject fascinating from both the chemistry & the religious aspects.
Even a jew far removed from his homeland, and religion.(myself)... if given long enough will find that the meaning and the process are like all things, they are intertwined. Without perspective, we have no balance, without balance we lose our way. Finding the Tekhelet, after being far removed, is also the sign of a completed mission, and also perhaps the beginning of a new one. Shalom.
Hello, I am very impressed with your work Mr Sterman. May I ask if you think there will ever be any "resolution" to the question of whether or not "true (kosher?) tekhelet has been restored?"
I do not know if the very next logical step for this rabbi is making `Aliyah. He and his Orthodox counterparts should also learn much better Hebrew pronunciation, master it and enthusiastically support ascent to Har haBayit. The latter is of paramount importance. Those who do not support it are perpetuating Galut and Galut mode even if they actually make `Aliyah.
For this, RUclips was created.
Rav Menachem Ziemba, ended up in the Warsaw ghetto together with two other rabbis. They were offered a chance to get out, but they insisted on staying with their flock. He ruled in favor of the uprising, and, yes, the ruling make a difference to many people. (In general, the normal leadership - the Aguda (now UTJ) and the General Zionists (Chaim Weitzman's party) - was removed first by the Nazis (see Lucy D., War against the Jews), and thus the rebellion was in the hands of more fringe groups - the socialists (Labor) / Communists and the Revisionists (now Likud).)
