At the sound of their voicesThe voices refer to the seraphim, heavenly beings who are in the presence of God. Their proclamation of God's holiness is so powerful that it causes a physical reaction in the temple. This emphasizes the majesty and authority of God, as even the voices of His attendants have immense power. The seraphim's cry of "Holy, holy, holy" (
Isaiah 6:3) underscores the complete and perfect holiness of God, a theme that resonates throughout Scripture, such as in
Revelation 4:8.
the doorposts and thresholds shook
The shaking of the doorposts and thresholds signifies the overwhelming presence and power of God. In ancient Near Eastern culture, such physical manifestations were often associated with divine appearances or theophanies. This shaking can be compared to other biblical instances where God's presence causes the earth to tremble, such as at Mount Sinai (Exodus 19:18). It symbolizes the awe and reverence due to God and the transformative impact of His presence.
and the temple was filled with smoke
Smoke is often associated with the presence of God, as seen in the cloud that filled the tabernacle (Exodus 40:34-35) and the temple (1 Kings 8:10-11). It represents God's glory and holiness, creating a barrier between the divine and the human, emphasizing the need for purification and atonement. The smoke in Isaiah's vision also prefigures the ultimate sacrifice of Jesus Christ, who provides the means for humanity to enter into God's holy presence.

At the sound of their voices• Isaiah sets the scene with heavenly beings (v. 3) calling “Holy, holy, holy,” and their unified praise is so powerful that it reverberates through the entire sanctuary.
• Scripture often portrays God’s voice—and the voices that proclaim His holiness—as carrying tangible force (Psalm 29:3-9;Revelation 4:8-11).
• Taking the passage literally, we see that worship in heaven is not quiet background music; it shakes creation itself, reminding us that God’s glory is not merely perceived—it is experienced.
the doorposts and thresholds shook• The very architectural supports of the temple tremble. This is not poetic exaggeration but a physical reaction to divine presence, echoing events like Sinai where “the whole mountain shook violently” (Exodus 19:18) and the earthquake at Jesus’ resurrection (Matthew 28:2).
• By describing stationary, weight-bearing structures quaking, Isaiah underscores the absolute supremacy of God over what seems most stable in our world (Haggai 2:6;Hebrews 12:26-27).
• The shaking also foreshadows judgment: when God moves, nothing unholy can remain unmoved (Joel 3:16;Acts 4:31).
and the temple was filled with smoke• Smoke or cloud frequently signals God’s immediate presence and His unapproachable holiness—first inExodus 40:34-35 when the tabernacle was completed, later in2 Chronicles 5:13-14 at Solomon’s temple, and finally inRevelation 15:8.
• The literal filling of the temple makes clear that worship is now enveloped by God Himself; Isaiah cannot escape or distance himself from holiness (Isaiah 6:5).
• The smoke also graciously veils full glory, sparing Isaiah from instant destruction (Exodus 33:20;1 Timothy 6:16), yet it compels awe, confession, and readiness for service.
summaryThe seraphim’s thunderous praise shakes the temple’s very framework and floods it with smoke, vividly displaying God’s overwhelming holiness and authority. These literal events press the truth that divine worship is earth-shaking, God’s presence is tangible, and His glory both reveals and conceals, calling every witness to reverent submission and wholehearted obedience.

The posts of the door.--Better,
the foundations of the threshold.The words seem to point to the prophet's position as in front of the Holy of holies.
The house was filled with smoke.--The vision had its prototype in "the smoke as of a furnace" on Sinai (Exodus 19:18), in the glory-cloud of1Kings 8:10, and possibly in its lurid fire-lit darkness represented the wrath of Jehovah, as the clear brightness of the throne did His love. So inRevelation 15:8, the "smoke from the glory of God" precedes the outpouring of the seven vials of wrath'. The parallelism of the clouds of incense-smoke as the symbol of adoring prayer (Revelation 5:8;Revelation 8:4) suggests an alternative interpretation as possible; but in that case mention would probably have been made of the censers from which it rose. The incense-clouds of the Temple may in either case have been the starting-point of the mystic vision. . . .
Verse 4. -
The posts of the door moved; rather,
the bases of the thresholds shook (compare Revised Version). The shout of the seraphs shook the very foundations on which the thresholds of the gates of heaven rested - a testimony to the energy with which it was uttered.
At the voice of him that cried;
i.e. "at the voice of each and all."
The house was filled with smoke. "Smoke" is sometimes the mere sign of the presence of God, as in
Isaiah 4:5; but more often it indicates his presence in anger or judgment (see
Exodus 19:18;
Exodus 20:18;
Revelation 15:8). Here there had been no smoke at first, and we must suppose it, therefore, a sign of the anger which finds vent in ver. 9-12.
