Comment Comment by fortran77 In the Hebrew bible, there's a commandment to put fringes on garments with corners and to put a blue thread in them:דבר אל־בני ישראל ואמרת אלהם ועשו להם ציצת על־כנפי בגדיהם לדרתם ונתנו על־ציצת הכנף פתיל תכלת(from "Numbers 15" in common termonology).Because we don't know the dye that was used 3000 years ago, today most omit the blue thread, but some people claim that they know what it was (see https://www.chabad.org/library/article_cdo/aid/530127/jewish...) and wear fringes with blue.(It's from a cuttlefish, the "chilazon")Personally, I wear the blue thread, but I don't think we really know for sure what they used back then. parent fortran77 2 years ago

Personally, I wear the blue thread, but I don't think we really know for sure what they used back then.
