Isaiah 6:4 (KJV)

What does Isaiah 6:4 mean?

Isaiah 6:4 describes how the very foundations and doorposts of the temple shook at the voice of the one calling out, and the entire house was filled with smoke. This scene shows the overwhelming power and holiness present in Isaiah’s vision of God.

In this verse, Isaiah is witnessing a vision inside the temple, where he sees the Lord on a throne and hears seraphim (heavenly beings) calling out. The shaking of the doorposts and the filling of the temple with smoke highlight the awe and fear that come with God’s presence. This moment sets the stage for Isaiah’s response to God’s holiness and majesty.

The Hebrew behind Isaiah 6:4

• The word for "posts" is אֻשִּׁים (’ussim), which refers to the foundational supports or doorposts of a building. Their movement suggests a dramatic, physical reaction to the divine voice, emphasizing God’s power.
• The word for "moved" is נוּעַ (nu‘a), meaning to shake or tremble. This word often describes earthquake-like shaking, underlining how the presence of God causes even the strongest structures to tremble.
• The word for "smoke" is עָשָׁן (‘ashan), which can symbolize God’s glory, presence, or even mystery. In the Old Testament, smoke often appears when God is near, such as at Mount Sinai, showing that this is a moment of divine encounter.
