What two things happened when the voice of the seraphim cried out?

The correct response highlights that when the voice of the seraphim cried out, it caused significant physical disturbances in the environment. Specifically, the posts of the door were shaken, indicating a powerful force or divine presence, and the house was filled with smoke, which symbolizes the manifestation of God's glory and holiness. This imagery is drawn from Isaiah 6:4, where the description emphasizes both the profound impact of the seraphim's declaration and the sanctity surrounding God's presence. The smoke further represents both the mystery of God and the awe that His holiness inspires, reinforcing the atmosphere of reverence in the vision Isaiah recounts. This understanding helps to grasp the dramatic and overwhelming nature of the divine encounter documented in this scripture.
