Introduction to Psalm 99
Psalm 99 Text: YHWH malakh and the Throne of the Cherubim
Psalm 99 opens with the enthronement formula that unifies the royal hymns of the Psalter: YHWH malakh, yirg'zu ammim, yoshev keruvim tanot ha'aretz — "YHWH reigns, let the peoples tremble; he is enthroned upon the cherubim, let the earth quake" (Ps 99:1 MT). The image of YHWH yoshev keruvim ("enthroned upon the cherubim") refers to the cultic reality of the Ark of the Covenant: God speaks from above the mercy seat between the two cherubim (Exod 25:22). Psalm 99 text thus situates divine kingship within the context of the Temple and worship, where the sovereign of the cosmos makes himself accessible to his community. Verse 2 articulates the tension between local presence and universal lordship: YHWH b'Tziyyon gadol, v'ram hu al kol ha'ammim — "YHWH is great in Zion and he is exalted over all the peoples" (Ps 99:2 MT). The greatness of YHWH is not circumscribed to Mount Zion but extends to all nations.
Psalm 99 Commentary: The Structure of the Trisagion
The structural characteristic of Psalm 99 is the triple proclamation of the refrain kadosh hu ("holy is he"), distributed at three junctures of the text as a liturgical refrain: at verse 3 — yodu shim'kha gadol v'nora kadosh hu ("let them praise your great and awesome name, holy is he"); at verse 5 — rom'mu YHWH Eloheinu v'hishtakhavu lahadom raglav, kadosh hu ("exalt YHWH our God and worship at his footstool, holy is he"); and at verse 9 — ki kadosh YHWH Eloheinu ("for YHWH our God is holy"). This triple schema gave rise to the Qadosh, Qadosh, Qadosh (Isa 6:3) of the liturgical Trisagion: in the synagogue it is the nucleus of the Qedushah, the highest section of the prayer of the eighteen benedictions; in Christian liturgy it is the Sanctus of the Mass (Rev 4:8). Verse 4 specifies the ethical content of divine holiness: oz melekh mishpat ohev, attah konnanta meisharim mishpat u'tzedaqah b'Ya'aqov attah asita — "you, O mighty king, love mishpat; you have established equity, justice and righteousness in Jacob" (Ps 99:4 MT). The qedushah ("holiness") of YHWH is not absolute separation from the world but ethical commitment in history.
Psalm 99 Explanation: Moses, Aaron and Samuel in Intercession
The second section (vv. 6-8) introduces three paradigmatic figures of intercession: Moshe v'Aharon b'kohanav, uShmuel b'kor'ei shmo, qor'im el YHWH v'hu ya'anem — "Moses and Aaron among his priests, and Samuel among those who call upon his name; they called to YHWH and he answered them" (Ps 99:6 MT). The triad Moses-Aaron-Samuel encompasses the three dimensions of mediation in ancient Israel: prophetic, priestly and judicial. Verse 7 describes the mode of divine communication: b'ammud anan yedabber aleyhem, sham'ru edotav v'khoq natan lamo — "in the pillar of cloud he spoke to them; they kept his testimonies and the statute that he gave them" (Ps 99:7 MT). The ammud anan ("pillar of cloud") is the pre-eminent symbol of the divine presence that accompanies the people in the wilderness (Exod 13:21). The psalm concludes with an invitation to proskynesis on the holy mountain: rom'mu YHWH Eloheinu v'hishtakhavu l'har qodsho, ki kadosh YHWH Eloheinu — "exalt YHWH our God and worship at his holy mountain, for YHWH our God is holy" (Ps 99:9 MT). The holiness of YHWH requires the response of prostration: kadosh hu is not only an attribute to contemplate but a reality to conform to in worship and in life.
