Some Bibles even have a heading, to show when the subject has shifted.
And the one you quoted uses a heading clarifying that both sections were to be repeated to the "king of Tyre".
In fact, none use a title indicating Ezekiel was to go speak to an angel.
Verse 11 startes a direction for Ezekiel to sing a lamentation to "him" (typically a funeral song). With v18-19 clarifying his death. We noticed you stopped the lament mid-stanza.
Ezekiel 28:18-19 “You defiled your sanctuaries By the multitude of your iniquities, By the iniquity of your trading; Therefore I brought fire from your midst; It devoured you, And I turned you to ashes upon the earth In the sight of all who saw you. All who knew you among the peoples are astonished at you; You have become a horror, And shall be no more forever.”’”
Is it your opinion that an angel trades, is turned to dust and will be "no more"?
