Pomegranates, bells, and tzitzis[1]
ועשית את-מעיל האפוד כליל תכלת: ועשית על-שוליו רמני תכלת וארגמן ותולעת שני על-שוליו סביב ופעמני זהב בתוכם סביב
You shall make the me’il of the eiphod entirely techeiles. You shall make on the bottom of it pomegranates of techeiles, argaman, and tola’as shani, on the bottom all around, and golden bells amongst[2] them all around[3]
One of the garments of the Kohen Gadol is the me’il, a type of blue cloak. There’s a dispute about exactly how it looked. Some say[4] it was like a regular long shirt. In contrast, the Rambam describes[5] the me’il as not having sleeves. Rather, it was divided into two corners from the neck downwards. Meaning, it is not attached except adjacent to the neck. This sounds similar to what our tallis katan looks like today, which is a four cornered garment[6]. One of the unique features of the me’il is the bottom of it had threads spun and woven together to resemble pomegranates, as well as golden bells. The latter were there so all would hear the Kohen Gadol as he came[7].
