Scholar’s Study: The Great Tekhelet Debate

In the Archaeological Views column “The Great Tekhelet Debate—Blue or Purple?” (BAR, September/October 2013) Baruch and Judy Taubes Sterman of the Jerusalem-based Ptil Tekhelet Foundation suggest that God’s chosen color for the ancient Israelites was a sky-blue derived from murex dye. In a letter to BAR, Professor Zvi C. Koren, director of the Edelstein Center for the Analysis of Ancient Artifacts at the Shenker College of Engineering and Design in Ramat Gan, Israel, criticizes the Stermans’ analysis, to which the Stermans have replied. In a new letter published on January 2, 2014, Koren responds to the Stermans’ letter.

    It’s is about what the color means, not the snail. The murex species snails of the Red Sea that the Redeemed Israelites crushed
    crushed under foot produces a darker blue. Blue represents the end result of righteousness under pressure/fire. The
    Israelites under pressure produced the sapphire blue dye. Sapphires are produce by earth with aluminum under fire.
    The tekhelet represents the name of God in the midst of his word that has been proven under fire.
    Purple is a mixture of Red and Blue. Red the color of exposed blood thus sin is an impure representation. The culture
    And relevant context should always be a major portion of scientific study. I greatly am appreciate of this article. Todah for
    Sharing it.

    The Phoenicians kept secret their source of the Romans ‘royal purple’ which they sold in trade.The Phoenicians, neighbors of the Israelis, also spoke Hebrew. They were the foremost traders of the ancient world, going all the way to Britain for Tin, and also to Africa. Carthhage was a colony.

    I have trouble believing that an unclean animal was (and apparently still is) used to obtain a dye for manufacturing one of Yahweh’s Commandments (tsitsith).
    Leviticus Chapter 11 clearly outlines what creatures are clean and which are unclean. Snails are among the unclean. One could have a pet snail while it is still alive, but the unclean creatures’ carcasses are not to be touched, they are abhorrent and detestable. As I understand it, the snails are crushed (killed), producing carcasses in the process of squeezing out a drop of blue dye to be collected. Isn’t this dye (part of the guts?) essentially part of the carcass?
    Lev. 11:10 “But whatever is in the seas and in the rivers, that do not have fins and scales among all the teeming life of the water, and among all the living creatures that are in the water, they are detestable things to you,
    11 and they shall be abhorrent to you; you may not eat of their flesh, and their carcasses you shall detest.
    12 ‘Whatever in the water does not have fins and scales is abhorrent to you.
    35 ‘Everything, moreover, on which part of their carcass may fall becomes unclean; an oven or a stove shall be smashed; they are unclean and shall continue as unclean to you.”

    Using and wearing part of a snails carcass is almost as bad as making a Bible cover out of pig skin, and saying that it doesn’t matter (Bible covers that are Berkshire Leather are described by Ingram Publishing as “High-quality pigskin…”, the same as well for their “Genuine Leather” Bible covers, they are made from the swine’s skin).
    I am reminded of the abominable act of Antiochus IV Epiphanes slaughtering a pig on the Altar in the Temple at Jerusalem, thereby defiling the whole place! Detestable!

    Please convince me that I am wrong about the dye. Meanwhile, I will continue to wear tsitsiths that are made with regular blue dyed strings purchased from the local stores.

  4. Theresa says

    I am in agreement with Tom. It doesn’t make any sense at all. Job 14:4 says ‘who can bring something clean from something that is unclean?’

  5. Kristina says

    Yep.

  6. WILLIAM says

    I have trouble seeing how anyone could argue for an extramundane presence, perhaps even out of the universe, which acts upon human history. If you equate god and universe–or better Buddhist emptiness–you are not concerned with a personality and thus don’t have to so spectacularly fly in the face of reason. That said, if we have a universe that is interconnected and we don’t have do go outside of it, then how in the world could such a universe be in the slightest way ever intervene in our lives–it IS us, all, and it not above it. Such a universe couldn’t possibly care about the exact color of a religious’s groups so-called sacred things, could it? Such biblical literalism as I just have read about the type of blue, the prohibition of the murex as dirty and unclean–the whole argument seems utter silly and made of the stuff that brings all religious groups to periodically indulge in ethnic cleansing of their so-called impure, heretical, or pagan neighbors. Please folks. A little compassion and common sense please.

    Tom,

    Scientists say that we only use about 10% of our brain. Einstein perhaps used 15%. So, for us average ten-percenters, it is difficult for us to believe LOTS of different things, simply because the so called “ten-percenters” have not got the necessary brain power to arrive at the truth of the matter.

  8. yosef says

    to tom regarding the verse in job it means who can make from unclean clean …exept for u oh G-Dgd the one who constantly daes it semen is ucnlean yet a human baby born from that is clean and pure as far as the snail the bible tells to make techelet we dont kno what it is the talmud says we have a tradition from moses. G-D told him it is to be made from this snail called chilazon a not pure fish that can not be eaten but GD chosethe this fisha for itu praduces the colourbbq of thethe sky so weim should producehave string that remindis us he iswas the one above – now have scientific confirmation of our tradtiond that that was used

  9. Krzysztof says

    All names from before 8th century are fictions, literary devices- says JHWE- use your brain, divine one (Genessis 1:27); also Moses!

  10. Alice says

    Krzysztof, your claim concerning “names”, as you call them, is demonstrably false. The ruler lists of Genesis have been verified.

    Moses and his family were Horites (Horim) and the sacred blue of the Horites was indeed a sky blue. It appears on the murals of ancient Egyptian monuments. This was dye from the Nile Hexaplex trunculus. The Tyrian method for producing purple dye from Hexaplex trunculus has not been successfully reproduced because the purple hue quickly degrades, resulting in blue only. The Tyrians most certainly added something to stabilize the purple hue, probably a plant substance.

  11. Alam says

    I think you are all a little (or a lot) crazy.

  12. Jack says

    To Tom- I agree with you that it is strange that from an unkosher snail we would get the dye used for the Kohen Gadol and others. However, the Tachash, whose skin is used as a waterproof cover for the Mishkan, may not have been kosher. I quote from Rav Kook-

    “Like the special generation of the desert, the Mishkan embodied timeless aspects of the universe. The holy sanctuary of the desert was not a matter of specific morality for a particular era, but encompassed the expanse of all times and all things. It reflected the beautiful harmony of the entire universal order, and the divine aim of elevating all of creation. It was therefore possible that its outermost covering was made from an impure animal. The tachash, with its many hues and colors, represented the ultimate value of the many forces in the world, in all their variations. Its inclusion in the Tabernacle, albeit in its outermost layer, enabled an expression of our intellectual recognition of God’s essential unity, that nothing exists outside of Him, and that all was created in His Glory.”

  13. Jose says

    When a person is without the Lord. He/she are unclean, dirty, detestable, and unjust. When they came repented to Our Lord, He crushed them from inside out. Then, they become a new person in the spiritual sense. Our Lord extracts from them Gold, which most valuable and precious metal. If there is anything impossible for G-d?

  14. Steven says

    Is it possible that the tradition/learning that was passed orally was to avoid eating a snail because they could cause paralysis?

  15. Steven says

    There was quite a large amount of blue used in Egypt before and during the time associated with Moses so the source of those colors for painting and dyeing was unlikely from a mollusk. And the biblical/historical/theological/social meanings of the color blue is quite a different topic from the source of the material.

  16. ilan says

    A couple of things that puzzle me.

    1. We have the term “over-harvesting” to describe the collection of species of flora and fauna to the extent that they can no longer maintain a population balance to equal to that which is being taken away. With the Murex or like genus, it would seem that something in great demand as this could not have avoided extinction or become so hard to find, especially as it was an easy catch, dwelling among shallow reefs and rocks close to shore. By all accounts it seems the Murex population where it would have been obtainable, would have been devastated.
    If you want ot mass produce Murex today then you better start setting aside protected reefs and such to allow a populaiton boom and then afterwards a limit, like on Abalone, on how many snails and what age you may take. Good Luck. I thinkn Indigo and other plants are the way to go.

    2. Poster Tom has a problem, a reasonable one I believe, with the uncleanliness of the snail itself, which actually is by habit a predator, eating other creatures to survive. The species of Non Kosher animals mentioned in the Torah reference many of them as living off the carrion of other animals and so are considered disgusting and non kosher. This is my problem with Honey as well. The Rabbis used to argue that the honey was a natural product of the Bee and had nothing to do with its biological makeup. Maybe because they never saw anything other then the usual filterable items in the honey to make them think that there was something of the bee itself inherent in the honey, though its contact with the bee itself in any form is a question of degrees if you wish to maintain the mirage that honey magically appears out of the nectar and without help from the insect. But now we know that the the non kosher Bee does contribute enzymes to help the transformation from pollen to Honey. Yet they seem to have no problem with this still. There is no question that the Honey is tainted by the unclean secretions of the bees stomach.
    I favor the commentators who define a land flowing with milk and honey to be referring to date honey, made by a process which in short,thru heat and compression gives you a runoff of sweet date honey, and its available especially if you look in the Vegan stores. Its delicious.The blind eye to bee spit in the Nectar is just so much self delusion or a hear no evil see no evil on order not to have to give up honey.
