What were the Choshen and the Eifod, respectively?
Rashi (in Pasuk 6): The former was a kind of ornament that was worn next to the heart; the latter, a kind of apron (that was worn at the back from the waist down 1 and) that had side-straps 2 which were tied in front as well as shoulder-straps that were affixed to it, one on either side of the Eifod. 3
Rashbam (in Pasuk 7): The former was a kind of bag, 4 the latter, a kind of garment that was wrapped round the Kohen Gadol - both at the back and at the front.
See Rashi, who cites his source for this.
A belt that was woven together with the Eifod - out of the same threads, with pictures of Keruvim like the Eifod itself, that extended around the Kohen Gadol's waist and was tied in front (Rashi, Pasuk 7).
The Torah will provide more details of all eight Begadim in the course of the Parshah.
To house the Urim ve'Tumim, which will be described later in the Parshah.
What is the definition of "Kesones Tashbeitz"?
Rashi, Rashbam: Targum Onkelos and Targum Yonasan: It means a shirt with ornamental settings. 1
Which one generally makes in golden ornaments to house precious stones and pearls - as we find later by the Efod in Pasuk 11 (Rashi).
What was the basic difference between the Me'il and the Kutones?
Rashi: They are both a type of tunic (shirt) with sleeves, only whereas the latter is an undershirt that is worn next to the skin (like a vest), the former is worn on top of it like a shirt).
What was the "Mitznefes"?
Rashi and Rashbam: The "Mitznefes" was a hat. 1
Ramban (in Pasuk 31): It was a turban measuring sixteen Amos, that wound round and round the Kohen Gadol's head, as opposed to the hat of the Kohen Hedyot, which was similarly wound around the head, but spiraled upward. 2
Synonymous with 'Migba'as' - in Pasuk 40 (Rashi).
Which explains why the Torah sometimes refers to the Kohen Hedyot's head-covering as Migba'as, though it refers to that of the Kohen Gadol as Mitznefes, exclusively. See also Rav Chavel's footnotes. Basically however, the Kutones, the Mitznefes and the Avneit of the Kohen Hedyot were the same as that of the Kohen Gadol (Ramban, 39:27-28).
Where exactly was the Mitznefes worn?
Rashi (in Pasuk 37): It was worn above the forehead, with space in between it and the Tzitz to don Tefilin.
What was the difference between the "Avneit" and the "belt of the Efod"?
Rashi and Seforno: The former was to gird the Kutones, the latter, the Me'il.
Why did Hashem omit the pants and the Tzitz from the list?
Rashbam and Ba'al ha'Turim: Because the pants which were not visible, were not for Kavod and Tiferes.
Ba'al ha'Turim: He omitted the Tzitz because it was not a Beged. 1
Moshav Zekenim: The underpants are not mentioned here because they were not required for the Avodah, only to cover their Ervah.
R. Tam (in Tosfos Nazir 54b DH Eretz) maintains that it is a Beged, since the command "Ve'asisa Bigdei Kodesh" incorporated the Tzitz. The Maharsham (2:94) queries this however, since the Tzitz is not listed here - only later in Pasuk 36.
To whom is "u'le'Vanav" referring?
Oznayim la'Torah: It refers to Aharon' descendents, who assumed the Kehunah Gedolah after him - and the Torah writes "Lechahano Li" in the singular, 1 because there was only one Kohen Gadol at a time.
Refer also to 28:1:151:2 and note.
