The Biblical commandment appears in Exodus 28:31-35:
“And you shall make the robe of the ephod completely of blue wool.
Its opening at the top shall be turned inward; its opening shall have a border around it, the work of a weaver. It shall have [an opening] like the
opening of a coat of armor; it shall not be torn.
And on its bottom hem you shall make pomegranates of blue, purple, and crimson wool, on its bottom hem all around, and golden bells in their midst all
A golden bell and a pomegranate, a golden bell and a pomegranate, on the bottom hem of the robe, all around.
It shall be on Aaron when he performs the service, and its sound shall be heard when he enters the Holy before the Lord and when he leaves, so that
he will not die.”
(Judaica Press Complete Tanach).
It was fashioned by Yehudit Avraham, woven in the manner of the Navajos of the Southwestern United States, and features the biblically commanded seventy-two bells and seventy-two pomegranates alternating around its hem.
It joins the Ephod (Exodus 28:4), and the Choshen, or breastplate, featuring the twelve precious stones associated with the twelve Tribes of Israel: Odem, (ruby), pitdhah, (emerald), bareket, (topaz), nofech, (carbuncle), shafir, (sapphire), yahalom, (quartz crystal), leshem, (jacinth), shevo, (agate), achlamah, (amethyst), tarshish, (chrysolite), shoham, (onyx), and yashfeh (opal), (Exodus 28:17-21).
Rabbi Chaim Richman explained to Arutz Sheva that this is the first robe woven out of techelet in two thousand years.
In the near future, the Institute plans to embark on another major project: the production and supplying of the Torah-specified white garments of the ordinary
priests for every male Jewish descendant of Aaron. “Every Kohen from all over the world, will be given the opportunity to register and order his own uniform
so that he can be ready to serve in the rebuilt Holy Temple,” Richman said.
“May it be thy will, Lord our God and God of our fathers, that the Temple be speedily rebuilt in our days, and grant us a share in thy Torah.
There we will serve thee with reverence, as in the days of old and as in former years.
Then the offering of Judah and Jerusalem will be pleasing to the Lord, as in the days of old and as in former years.
