הַמִּזְבֵּ֡חַ עֵ֣ץ שָׁלוֹשׁ֩ אַמּ֨וֹת גָּבֹ֜הַּ וְאָרְכּ֣וֹ שְׁתַּֽיִם־אַמּ֗וֹת וּמִקְצֹֽעוֹתָיו֙ ל֔וֹ וְאָרְכּ֥וֹ וְקִֽירֹתָ֖יו עֵ֑ץ וַיְדַבֵּ֣ר אֵלַ֔י זֶ֚ה הַשֻּׁלְחָ֔ן אֲשֶׁ֖ר לִפְנֵ֥י יְהוָֽה׃
Mezbah itu terbuat dari kayu, tingginya tiga hasta dan panjangnya dua hasta. Sudut-sudutnya menyatu dengannya, dan bagian panjangnya serta dinding-dindingnya terbuat dari kayu. Lalu ia berkata kepadaku: “Inilah meja yang ada di hadapan Yang Mahakekal.”
Rabbeinu Yonah
However, three who ate at one table and said upon it words of Torah - it is as if they ate from the table of the Omnipresent, blessed be He, as it is said (Ezekiel 41:22): "And he said to me, this is the table that is before the Lord": And the expression, "And he said," is [referring to an] individual, as you see [with] "And the Lord said to Moshe," which is individual, as He was speaking to Moshe alone. And when the verse wants to make the thing communal - for Moshe to say it to Israel - it is written, "saying"; which is a communal language. The explanation of "he said" by itself without "saying" is that He explained it to Moshe only and not that others should hear it. Also this [in] which it is stated, "And he said to me, this is the table," is an expression of "and he said" that specifies that this table is from below. Such that you should not think that it specifies that the table is from Above (the sacrificial table of the Temple offerings). And even though this is not a proof for the matter, it is a hint to the matter - as is the custom of our rabbis to [use as support] in several places.
English Explanation of Pirkei Avot
But, if three have eaten at one table, and have spoken there words of Torah, [it is] as if they had eaten at the table of the All-Present, blessed be He, as it is said, “And He said unto me, ‘this is the table before the Lord’” (Ezekiel 41:22) The verse in Ezekiel is discussing the altar, yet it refers to it as a “table”. This fact is “midrashically” interpreted by Rabbi Shimon to mean that sometimes a normal table can become an altar. This is so when the meal has been accompanied by the study of Torah.

"as it is said (Ezekiel 41:22), 'And he said to me, this is the table that is before the Lord'": Immediately when he speaks words of Torah, it is called a "table that is before the Lord." And some say that it comes out from the beginning of the verse, as it is written, "The altar is three amot" - do not read [it as] amot, but rather eemot (mothers or foundations), as in, there is a foundation (priority) to how a verse is written. Three corresponds to Torah, Prophets and Writings; and some say to Sripture, Mishnah and Talmud - [meaning] that a person must speak about them over the table, and then it is called "a table that is before the Lord." So explained Rashi.
