Daniel 4:31

While the word was in the king's mouth, there fell a voice from heaven, saying, O king Nebuchadnezzar, to thee it is spoken; The kingdom is departed from thee.

While the word was in the king's mouth, there fell a voice from heaven, saying - in the very act of speaking, so that there could be no doubt as to the connection between the crime and the punishment. So in the case of the rich fool, God's voice of judgment suddenly broke in upon his voice of self-seeking covetousness. Compare also the stroke of God upon Herod, just after his "oration," wherein he gave not the glory to God, but suffered the people's blasphemous adulation, "It is the voice of a god, and not of a man" (Acts 12:21; Luke 12:19).

O king ... to thee it is spoken - notwithstanding thy kingly power, to thee thy doom is now spoken: there is to be no further respite.
