Psalms 99
Psalm 99 is the last in a remarkable run of songs - Psalms 93 and 95 through 99 - all of which announce the same staggering fact: the LORD reigneth. Earthly thrones rise and topple, empires come and go, but over them all sits a King whose rule never ends. This psalm takes that announcement and presses it to its sharpest point. It is not chiefly about God's power, or even His justice, though both are here; it is about His holiness - the quality that sets Him utterly apart from everything He has made.3
The structure is unmistakable once you see it. Three times the psalm sounds a refrain on the holiness of God: for it is holy (v. 3), for he is holy (v. 5), and for the LORD our God is holy (v. 9). Each refrain closes off a movement, and each call to worship grows more insistent - from let them praise, to exalt ye the LORD… and worship at his footstool, to exalt the LORD our God… and worship at his holy hill. The threefold word is no accident. It is the same triple cry the prophet Isaiah heard from the seraphim above the throne, Holy, holy, holy, is the LORD of hosts (Isa. 6:3), and the same song the living creatures sing without ceasing around the throne of heaven, Holy, holy, holy, Lord God Almighty (Rev. 4:8). To read Psalm 99 is to overhear, in the temple at Jerusalem, the worship of heaven itself.2
And yet - this is the heart of the psalm - the holiness that makes the earth tremble does not make God unreachable. The King who sitteth between the cherubims is the same King who loveth judgment and who answered when Moses, Aaron, and Samuel called upon Him. Most astonishing of all, He is the God who forgavest them (v. 8). The psalm holds together two things we are tempted to keep apart: a God so holy that the people must tremble, and a God so gracious that He hears the cry of those who seek Him and pardons their sin. The trembling and the welcome belong to the same throne. The whole movement of the song is from awe to nearness - from let the earth be moved to worship at his holy hill - and it never once pretends that the nearness has cheapened the holiness.1

Psalm 99:1-3The LORD Reigneth; Let the People Tremble
1The LORD reigneth; let the people tremble: he sitteth between the cherubims; let the earth be moved. 2The LORD is great in Zion; and he is high above all the people. 3Let them praise thy great and terrible name; for it is holy.
The psalm opens like a herald's proclamation: The LORD reigneth. Two words in Hebrew, and they carry the weight of the whole song. This is not a wish or a hope; it is a present fact. Whatever else seems to be in charge of the world - armies, empires, the proud who rise against the weak - the truth underneath all appearances is that the LORD is on the throne, and His rule is unbroken. And notice the immediate response the psalm calls for: let the people tremble… let the earth be moved. The Hebrew behind be moved pictures the ground shaking, staggering, unsteady before the presence of its King. This is not the cosy reign of a distant figurehead. It is the rule of a holiness so total that creation itself quivers in its presence. But hold that trembling lightly for a moment, because the psalm will not leave us there. The same King before whom the earth shakes is, by verse 6, the One who answered those who called on Him, and by verse 8 the One who forgavest them. The trembling is real - but it is the trembling of awe before a King who turns out to be merciful.
The LORD is great in Zion; and he is high above all the people (v. 2). Two directions of greatness stand side by side here. He is great in Zion - present, near, dwelling among His people in a particular place, the city where the ark stood and the worship rose. And He is high above all the people - exalted over every nation on earth, not the local deity of one city but the King of all. This is the tension the whole psalm lives in. The God of Zion is not small because He is near; His nearness in one place does not shrink His rule over all places. He stoops to dwell with His people without ceasing for an instant to be high above them. A lesser god, brought close, would be diminished; this God is fully present in Zion and fully exalted over the earth at the same time. The same breath that says He is great in Zion insists that He is high above all the people - and the worshipper is meant to feel both at once: this is our God, and this is the God before whom the nations are nothing.
Psalm 99:4-6They Called Upon the LORD, and He Answered
4The king's strength also loveth judgment; thou dost establish equity, thou executest judgment and righteousness in Jacob. 5Exalt ye the LORD our God, and worship at his footstool; for he is holy. 6Moses and Aaron among his priests, and Samuel among them that call upon his name; they called upon the LORD, and he answered them.
The psalm now tells us what this King does with His power: The king's strength also loveth judgment; thou dost establish equity, thou executest judgment and righteousness in Jacob (v. 4). It is a crucial line, because raw power without righteousness is the most frightening thing in the world - a throne that can do anything and answers to no one. But the strength of this King loveth judgment. His power is wedded to justice; He does not merely have might, He loves what is right and bends His strength toward it. And the verbs are active and ongoing: He establishes equity, He executes judgment and righteousness - not as occasional acts but as the steady character of His reign. Equity means evenness, fairness, the straight measure that does not tilt toward the powerful. So the holiness that made the earth tremble in verse 1 turns out to have a moral shape: it is the holiness of a King who cannot be bribed, who will not let the strong devour the weak, who governs Jacob with unbending fairness. This is why His holiness is good news and not merely terror. A holy King who loveth judgment is exactly the King the oppressed have always longed for - and exactly the King the proud have always had reason to fear.
Now the psalm does something tender and surprising. Having lifted God so high - enthroned above the cherubim, exalted over all peoples, holy beyond approach - it suddenly names three men: Moses and Aaron among his priests, and Samuel among them that call upon his name; they called upon the LORD, and he answered them (v. 6). These are not legendary heroes summoned to display God's power; they are named as those who called, intercessors who stood before God on behalf of the people. Moses pleaded for Israel when judgment hung over them; Aaron stood between the living and the dead with his censer; Samuel cried to the LORD all night for a people who had rejected him. And the refrain over all three is the same: they called upon the LORD, and he answered them. Here is the answer to any fear that holiness means distance. The most exalted God in all of Scripture is, in the same psalm, the God who answers when His people cry to Him. The trembling of verse 1 and the answered prayer of verse 6 are held in a single hand. He is not so high that He cannot hear; the height is precisely the measure of how astonishing it is that He bends to listen at all.
Psalm 99:7-9A God That Forgavest Them
7He spake unto them in the cloudy pillar: they kept his testimonies, and the ordinance that he gave them. 8Thou answeredst them, O LORD our God: thou wast a God that forgavest them, though thou tookest vengeance of their inventions. 9Exalt the LORD our God, and worship at his holy hill; for the LORD our God is holy.
The psalm reaches back to the founding memory of Israel: He spake unto them in the cloudy pillar: they kept his testimonies, and the ordinance that he gave them (v. 7). The cloudy pillar is the pillar of cloud that went before Israel out of Egypt, that stood at the door of the tent where Moses met with God, that filled the tabernacle so that none could enter. It was the visible sign that the holy God was present and yet veiled - near enough to lead, hidden enough that no eye could presume upon Him. From within that cloud He spake: the transcendent King is also the speaking King, the One who does not leave His people to guess at His will but gives them His testimonies and His ordinance - His revealed word, His covenant instruction. Notice the response the verse records: they kept his testimonies. The God who speaks is to be obeyed; the word that comes from the cloud is not a suggestion but a charge. This is the same pattern as the cherubim of verse 1 - a presence both guarded and given. God hides Himself in cloud and yet speaks from it; He is unapproachably holy and yet will not stay silent. The holiness and the self-revelation are, once again, two sides of one God.
The psalm closes where it began - on the holiness of God - but the call has deepened. Exalt the LORD our God, and worship at his holy hill; for the LORD our God is holy (v. 9). Three times now the refrain has sounded: for it is holy (v. 3), for he is holy (v. 5), and now, fullest of all, for the LORD our God is holy. The earlier refrains were brief; this final one spells out the whole confession - not just it, not just he, but the LORD our God. And the place of worship has moved inward too: from the broad call to praise (v. 3), to His footstool (v. 5), to His holy hill (v. 9) - Zion, the mountain where He dwells. The whole psalm has been a steady approach: from the trembling earth, drawing nearer, until the worshipper stands on the holy hill itself, bowing before the King. And the thing that draws us in is the thing that holds us in awe - His holiness. We do not worship in spite of His holiness, edging closer once the danger has passed; we worship because He is holy. The repetition is not the psalmist running out of words. It is the only adequate response to having seen the King: to say the one true thing again, and again, and again - holy.
