Komentaryong Sumisipi para sa Mga Awit 122:5

"How does the city sit solitary?" To understand the word "Eichah" (how), we first need to examine what is stated in the Midrash: three people said "Eichah"—Moses, Isaiah, and Jeremiah. Moses said, "How can I bear alone" (Deuteronomy 1:12). Isaiah said, "How has the faithful city become a harlot" (Isaiah 1:21). Jeremiah said, "How does the city sit solitary" (Lamentations 1:1).
To understand this, it seems that it is already known that when Israel is not in a state of complete perfection, the Divine Name of God is not whole. When there is no justice in Israel, the Name of God is incomplete, and the letters Vav (ו) and Heh (ה) are missing, leaving only Yod (י) and Heh (ה). This is what David said: "The tribes of Yah are a testimony to Israel" (Psalms 122:4-5), and "there the thrones of judgment were set" (Psalms 122:5). Similarly, if sexual immorality, God forbid, increases in Israel, the Divine Name of God is not complete. Likewise, during the exile, the Divine Name is not whole, as it is written: "For the hand is upon the throne of Yah" (Exodus 17:16), and our Sages said, "From the day the Temple was destroyed, the world suffices with only two letters [Yod-Heh].
It is known that the word "Ach" (but) implies diminution, as the words "Ach" and "Rak" always indicate limitation. Therefore, Moses, who judged all of Israel by himself and found it difficult, said, "How can I bear alone" (Eichah: Ach Yah), meaning the Name of God is incomplete, leaving only Yod-Heh. Similarly, Isaiah, who saw the increase of immorality in Israel, as it is written: "Moreover the Lord said, because the daughters of Zion are haughty" (Isaiah 3:16), said, "How has the faithful city become a harlot" (Eichah: Ach Yah). And Jeremiah saw the noble lady (Jerusalem) in her degradation during the bitter exile, and since the world was content with just two letters, he said, "How does the city sit solitary" (Eichah: Ach Yah).
Similarly, when Adam sinned and ate from the Tree of Knowledge, the Divine Name was diminished, and therefore the Holy One, Blessed be He, said to him, "Where are you?" (Eichah: Ach Yah). It is known that the Torah is a "medicine of life" for those who uphold it, and it is pleasant. But for those who transgress it, it becomes a "poison of death," which causes "woe after woe." Therefore, at the giving of the Torah, God appeared with the Name spelled with a Mem and a Gimel, as it is said, "I am" (Anochi) with a pleasant utterance. However, during the exile, the Name was changed to one spelled with a Nun and a Heh, and it is said "How" (Eichah) instead of "I am" (Anochi), as the letter Heh implies "woe after woe." This is the meaning of the word "Eichah." Understand this well."

Thus is completed the Book of the Censuses¹²¹Such is the name given by the Sages to the fourth book of the Torah: “the Fifth of the Censuses” (Sotah 36b). [i.e., the Book of Numbers] and the standards of the hosts;
And to G-d, the G-d of hosts, be praises and thanksgivings, in hundreds, thousands, and myriads.
And as He has done for our ancestors great and awesome deeds,¹²²See Deuteronomy 10:21. may He bring about speedily in our days the end of the wonders.¹²³Daniel 12:6. A reference to the Messianic era.
May He build the House and the chambers and the border before the cells.¹²⁴Ezekiel 40:12.
And prepare there the thrones of the house of David,¹²⁵Psalms 122:5. This may also be a reference to the mysteries of the Cabala. See at end of Ramban’s Introduction to the Book of Genesis: “And He will show those who are pleasing to Him wonders from His Torah” (Vol. I, p. 16). and may our eyes behold it!
And may He in His mercies purify us of all [our] hidden [faults] and all errors,¹²⁶See ibid., 19:13.
And show us wondrous things from His Torah!¹²⁷See ibid., 119:18.
Amen. May His Will be so!
Finished and completed.

It is important that you understand how Onkelos’ translation reflects the fact that there were actually two thrones, one underneath the other, and that the words תחת רגליו כמעשה לבנת ספיר refer to the lower of the thrones which is described here as “beneath its feet,” i.e. beneath the feet of the higher throne. The lower throne appeared to these nobles of The Children of Israel as מעשה לבנת ספיר. (The concept of the two thrones appears already in Chagigah 14) It is a fact that there are two thrones. This is why our verse wanted to make clear to you that beneath the upper throne there is a lower throne to which the description of the vision seen by the nobles of the Children of Israel became privy as a result of their vision.
The three foundations of G’d’s throne which we mentioned earlier are actually six and this is the mystical dimension of the verse in the Book of Kings dealing with details of Solomon’s throne (Kings I, 10,19). We read שש מעלות לכסא, “six steps were leading up to the throne.” The reason for this was that Solomon in his wisdom wanted to include in the construction of his own throne the מעלות, “advantages or virtues” of both the thrones in the celestial regions concerning which it has been written in Psalms 122,5: “for there the throne of judgment stood, thrones of the house of David.” This is the meaning of Chronicles I 29,23: “Solomon sat on the ‘throne of the Lord.’” This description applies to times when Israel enjoyed G’d’s goodwill. On the other hand, in times of Divine anger at Israel, the applicable verse is Daniel 7,9: עד די כרסון רמיו, “I watched until thrones were set in place and the Ancient of Days took His seat....His throne was tongues of flame, etc.”
