This is seems to be an unlikely creature significant in Jewish culture, its a type of crustacean from the Mediterranean which of course all shellfish are unkosher. Actually I don’t think anyone eats this.
Part of social trip I did with my work is to visit this centre by the shore of the Mediterranean that show tourists these creatures. The reason why these things are prized as if you gather them up and dissolve their insides in a jar, you get a blue dye once mixed with some chemicals.
The Tzitzit, the four strings that dangle from under a religious Jew’s shirt have this blue dye. You can see blue stripes similar to this on a prayer shawl too.
Well, me and my fellow volunteers got about 30 of them I think.
Blue and purple dyes during the bible were expensive, so this was probably quite a profitable industry to get into.
The man who was giving the talk at the Tekhelet tour reminded us of this passage in the bible.
This is what the LORD Almighty says: “In those days ten people from all languages and nations will take firm hold of one Jew by the hem of his robe and say, ‘Let us go with you, because we have heard that God is with you.’”
Interesting as me and my colleagues who tried holding the man’s garment from US, Canada, South Africa, Japan, Holland, Paraquay, Korea, New Zealand, and Israel and UK – yep, at least 10!
