At ang apuyan ng altar ay labindalawang siko ang haba at labindalawang siko ang lapad, parisukat sa apat na panig nito.
Rashi
Woe, Ariel Jonathan renders: Altar of the Lord. Ezekiel, too, called it that, as it is said (43: 16): “And the altar (וְהָאֲרִיאֵל) twelve [cubits] in length,” [because of the heavenly fire that lay like a lion atop the altar, as we learned in Tractate Yoma (21b)]. Our Sages, however, explained it in reference to the heichal (the Temple proper), which was narrow from the rear and wide in the front.
English Explanation of Mishnah Middot
Rabbi Yose said: Originally, the complete area [occupied by the altar] was only twenty-eight cubits by twenty-eight, and it rose with the dimensions mentioned until the space left for the altar pile was only twenty by twenty. When, however, the children of the exile returned, they added four cubits on the north, and four on the west like a gamma, since it is said: “Now the hearth shall be twelve cubits long by twelve broad, square” (Ezekiel 43:16). Is it possible that it was only twelve cubits by twelve? When it says, “With four equal sides” (, this shows that he was measuring from the middle, twelve cubits in every direction. According to Rabbi Yose, the bottom square of the original altar was 28 x 28, leaving 20 x 20 for burning the wood, after room was left for the foundation, sovev, horns and walkway. This accords with the size of the altar built by Solomon according to II Chronicles 4:1. However, when the Israelites returned from the Babylonian exile, they built the altar larger than it was before. They added four amot to two sides of the altar, forming the shape of the Greek letter Gamma, which made the usable space of the altar 24 x 24. This number is derived from an interpretation of Ezekiel 43:16, according to which the altar was 12 x 12 amot. This number strikes Rabbi Yose as being impossibly small, probably because that would make it smaller than the altar of Solomon. Therefore, he posits that the measurements were taken from the center of the altar, and that 12 amot extended in each direction, leaving a space of 24 x 24.
