Thou wast perfect in thy ways. The glory of the King of Tyre was, the prophet goes on to say, conditional. He began his reign in righteousness, but afterwards iniquity was found in him. And the root of that iniquity was the pride of wealth engendered by the greatness of his commerce (Ezekiel 28:16).
He was no longer like the cherub who guarded the Paradise of God, but like Adam when he was east out from it. Wealth and pride had tempted him to violence and to wrong, and he was no longer an "anointed" or consecrated, but a profaned and desecrated, king.
The, "stones of fire," the thunders and lightnings of the Divine Majesty, should no longer protect him.
