וַיָּבֹא֙ הַמֶּ֣לֶךְ דָּוִ֔ד וַיֵּ֖שֶׁב לִפְנֵ֣י יְהוָ֑ה וַיֹּ֗אמֶר מִ֣י אָנֹכִ֞י אֲדֹנָ֤י יְהוִה֙ וּמִ֣י בֵיתִ֔י כִּ֥י הֲבִיאֹתַ֖נִי עַד־הֲלֹֽם׃
E il re Davide entrò e si pose a sedere davanti al Signore, e disse: «Chi sono io, o Signore Dio, e che cos'è la mia casa, che tu mi hai condotto fin qui?

עומד ומקבל – it follows that until here he was sitting, and we find that we learned that he would read in the Ezrat Nashim/courtyard of the women, for if he read in the courtyard of Israel/Ezrat Yisrael and all the more so, in a holier place than that, it would be prohibited to sit other than the Kings of the House of David that were permitted to them to sit in the courtyard, as it is written (2 Samuel 7:18): “Then King David came and sat before the LORD.”
Da'at Zekenim
ויאמר הנני, “He said: “I am at Your disposal.” G–d responded that though you showed your preparedness with the same word as your forefather Avraham when I called upon him, (to offer his son to Me as a sacrifice) this is not what I come to ask of you. We know from Proverbs 25,6: במקום גדולים אל תעמוד, “do not stand in the place of great men.” (do not aspire to be important actively or passively) Aaron was commanded to come close to holy sites, the altar, (Leviticus 9,7) Not so Moses. He had to shun a holy site. Neither was allowed to aspire to Royalty, as opposed to David. He acknowledged that G–d had brought him הלום, instead of as Moses: אל תקרב הלום. (Compare Samuel II 7,18 and Sh’mot Rabbah 2,6)
Rabbeinu Bahya
אדמת קודש הוא, “it is holy ground.” The word אדמת is in the construct form of the word קדש, i.e. Mount Sinai is holy ground. Compare Psalms 68,18 אדנ-י בם סיני בקודש, “the Lord is among them as in Sinai in holiness.” Now that Moses was only at the very beginning of his career as a prophet he was not yet allowed to step on this holy ground. The word הלום is itself a reference to the שכינה, as it is a word describing Majesty, Royalty (Shemot Rabbah 2,6). This is based on Samuel I 10,22: הבא עוד הלום איש?, “has anyone else come here?” [Samuel referred to Saul who was to be king, Ed.]. The word is again used in that sense in Samuel II 7,18: כי הביאותני עד הלום, “for He has brought me thus far?” [David acknowledging his position of King over Israel by grace of the Lord. Ed.] Seeing that the שכינה is emanated from a holy source, Moses was given his first inkling of the meaning of holiness in terms of “holy ground.”
Rashi
And Shlomo stood before the Altar of Adonoy. [As] it is written, “and Shlomo made a copper basin and had set it in the midst of the court, etc. and upon it he stood, and knelt on his knees.”15Even though a king of Yisroel is allowed to sit in the Beis Hamikdosh [See II Shmuel 7:18], Shlomo chose to stand.16II Divrei Hayomim 6:13.
