פּירוש אויף שמות 28:36

“You shall make a frontlet of pure gold” [28:36]. The priest had a golden plate on his forehead to his ears and there were holes on the edges into which silk strings were put, to tie it on the back of his head, so that it lay firmly on his forehead.²⁰Rashi, Exodus, 28:36–37.

Bahya also writes that it was a great wonder for the priests. They worked every day in the Temple in a simple shirt and barefoot. They suffered much cold, summer and winter. Therefore, they had to appoint experts who oversaw which ones were weak. There were many of them who were weak in their innards from the cold. They always had to immerse in the cold water and afterwards they had to go barefoot and in a shirt to do the service.²¹Bahya, Exodus, 28:43.

ציץ — This was a kind of golden Plate, two fingers in breadth, going round the forehead from ear to ear (Shabbat 63b).
