Symbolism, Imagery, Allegory
When God starts tearing into the Prince of Tyre, he says that he'll be thrown out of his state of Eden-like happiness and security by the guardian cherub that God's sent to look over him:
In the abundance of your trade you were filled with violence, and you sinned; so I cast you as a profane thing from the mountain of God, and the guardian cherub drove you out from among the stones of fire. (28:16)
This is the same kind of fearsome cherub with a flaming sword that God appoints to guard the gates of Eden after Adam and Eve are thrown out (Genesis 3:24). Definitely not these guys .
