As you can see in the chart above, Dovid Hamelech mentioned 33 things that praise Hashem. Because the inyan of Hod is praising Hashem, so Hod she'beHod - 33 - things praise Hashem!

And the word Halelu appears 10 times (besides for the first and last “Hallelu-ya”) which is keneged the 10 sefiros - the tenth one being מן הארץ! Noach was the 10th - איש האדמה (Maybe the Hilula of Rabbi Shimon is from the lashon “Halelu”). It’s also interesting that everything above the ground has the word Haleluhu - but from מן הארץ and on, all 23 things are נכלל in one הללוהו. But at the end of the kappitel, Dovid Hamelech sums it all up and says:

יְהַלְלוּ אֶת שֵׁם ה' כִּי נִשְׂגָּב שְׁמו לְבַדּו - הודו על ארץ ושמים

Your HOD, Hashem, is from both the Heavens and the Earth. Indeed, 33 things that praise Hashem, מבחינת הוד שבהוד.

And Dovid Hamelech himself was the 33rd generation from Adam Harishon. The bechinah of Hodaya - His name contains the shoresh of Hoda'ah - Vav and Daled. Just like Yehuda. Because Hodaa means "I could not do anything without you" - לית ליה מגרמיה כלום - and this is Malchus. (Hod is Malchus of Ze'ir Anpin).

It’s interesting that Dovid comes out as #33 - which is כנגד נער in the kappitel. The Zohar says on the Pasuk נער הייתי גם זקנתי which Dovid said, that נער is the bechina of Malchus… It makes sense because a נער has nothing of his own, he only copies what he sees in those above him… Also, Dovid had the purity of heart and emes of a child, like the pasuk says כִּי נַעַר יִשְׂרָאֵל וָאֹהֲבֵהוּ. And like the Zohar says about הוא ינהגנו על מות - לשון עלמות. And that’s why the Keruvim had faces of children, because when you see a child, you smile. And Dovid said כגמל עלי אמו כגמל עלי נפשי… And by the story of Michal it says:

ומיכל בת שאול נשקפה בעד החלון ותרא את המלך דוד מפזז ומכרכר לפני יהוה ותבז לו בלבה... ויאמר דוד אל מיכל לפני יהוה אשר בחר בי מאביך ומכל ביתו לצות אתי נגיד על עם יהוה על ישראל ושחקתי לפני יהוה… ונקלתי עוד מזאת והייתי שפל בעיני ועם האמהות אשר אמרת עמם אכבדה

With the energy, simplicity, purity, and with no airs about him… This is the quality of a נער.

וַיַּבֵּט הַפְּלִשְׁתִּי וַיִּרְאֶה אֶת-דָּוִד, וַיִּבְזֵהוּ: כִּי-הָיָה נַעַר, וְאַדְמֹנִי עִם-יְפֵה מַרְאֶה.
