The judgment of God is described as a theophany—an appearance of God—and riding on the clouds indicates his power. We also find the description of clouds as God's vehicle in other parts of Scripture (see Psalm 18:10–14 and Psalm 104:3). In a vision of Daniel, the Son of Man is associated with clouds (Daniel 7:13).
1 Oracle sur l'Egypte.Voici, l'Eternel est monté sur une nuée rapide, il vient en Egypte; Et les idoles de l'Egypte tremblent devant lui, Et le cœur des Egyptiens tombe en défaillance.
