Whereabouts on the Mizbe'ach ha'Zahav were the rings fixed?
See Oznayim la'Torah (citing the Ha'amek Davar). Panim Yafos: However, the Kohen placed blood on the corner, from the top and ran his finger down the edge (Yuma 58b)! We must therefore say that the rings were above the Mizbe'ach. Perhaps Yoma 58b discusses in the Beis ha'Mikdash, which did not have rings! Perhaps it is logical that placing the blood was the same in the Mishkan and in the Mikdash. (PF)
Even though in other places "Tzal'osav" means 'sides', here it means 'corners' - since the Torah already wrote "Al Sh'nei Tzidav".
Not a third of the way down, like the other Keilim, since due to its light weighjt, this was not necessary.
Bearing in mind that the Mizbe'ach ha'Ketores was square, it is not clear what it means by 'the width'?
The Seforno translates "Tzidav" as the sides that comprise the width and Tzal'osav" as the vertical walls.
The Mizbe'ach was only one Amah wide, so there was only one Amah between the poles. How could two people fit inside to carry it? We needed to say that the length of the Aron was between its poles, for two people could not fit inside the one and a half Amos of its width! (Refer to 25:12:1:1.)
Da'as Zekenim, Hadar Zekenim, Riva: Only one Levi carried it in front, and one in back. He stood in between the poles. 1
Panim Yafos #1: The rings were on opposite corners, so there were 1.4 Amos between the poles. This left enough space for two people to stand.
Panim Yafos #2 (Bamidbar 7:9): It says that they carried ba'Kasef (the known shoulder. i.e. the right one). We must say that one Levi stood outside the poles (on the left), and one stood between the poles.
Perhaps two people carried it, and each stood outside the poles. According to the opinion that the Levi'im were ten Amos tall, 2 there is barely room for one person's head to fit between the poles (PF).
Panim Yafos: The staves would be outside his shoulders! (Coffins fit into hollows in burial caves an Amah wide (Bava Basra 101a). This includes the width of the walls, and they must hold also wide people! The Gemara in Sukah 8a cites opinions that people are a. one Amah, or b. two thirds of an Amah wide; perhaps the former opinion included space between adjacent people (PF).
