Priestly golden head plate
The priestly crown or frontlet (צִיץ "ṣîṣ"/"tsiyts") was the golden plate or tiara worn by the Jewish High Priest on his mitre or turban whenever he would minister in the Tabernacle or the Temple in Jerusalem. Etymology. The root "tzitz" (צִיץ) means “to blossom” or “a flower” and as such is employed by the picturesque metaphors in Isaiah 27:6, 28:1, 40:7-8, floral descriptions of Solomon’s temple (1 Kings 6:18-35) and the blooming of Aaron’s rod (Num. 17:23). This latter instance is particularly interesting, because just as a "tzitz" appeared on the Aaron ’s rod so is the Aaronide high-priest supposed to wear a "tzitz" on his forehead. In addition to this, once in the Hebrew Bible, in Ezekiel 8:3, the word appears in the construction "tzitzit rosh" meaning “a mop of hair” and probably deriving from the metaphor of hair as the plants grown from skin. This is furthermore supported by a handful of rabbinic descriptions which compare the priestly "tzitz" to a flower in Shabbat 63b and Sukkah 5a. The Greek Septuagint renders the word in Exodus 28:36 and elsewhere "petalos" (πέταλος), "blossom," from which the English "petal" derives. Hebrew  Bible. The commandment regarding the crown is found in : The Tzitz was a small rectangular plate of solid gold, engraved in Hebrew letters with "HOLINESS TO THE LORD," and having holes drilled in each of the four corners through which blue cords were threaded () which held the tiara onto the High Priest's priestly turban. Traditionally, it is understood that one set of cords went around the High Priest's head at the base of the tiara, and the other went over the forehead, all meeting at the back of the head to hold the tiara in place. Talmud. According  to the Talmud, the wearing of the golden frontlet atoned for the sin of arrogance on the part of the Children of Israel (B.Zevachim 88b). The Talmud in Shabbat 63b describes the "tziytz" as encircling the High Priest's forehead “from one ear to the other.” Rabbi Abraham Isaac Kook suggested that this emphasis on the High Priest's ears — organs for listening — indicates that he needed to be particularly "receptive to the inner voice of elevated thought."
