Jezekiel 28:17

17 Thy heart has been lifted up because of thy beauty; thy knowledge has been corrupted with thy beauty: because of the multitude of thy sins I have cast thee to the ground, I have caused thee to be put to open shame before kings.

Jezekiel 28:17 In-Context

15 Thou wast faultless in thy days, from the day that thou wast created, until iniquity was found in thee.
16 Of the abundance of thy merchandise thou hast filled thy storehouses with iniquity, and hast sinned: therefore thou hast been cast down wounded from the mount of God, and the cherub has brought thee out of the midst of the stones of fire.
17 Thy heart has been lifted up because of thy beauty; thy knowledge has been corrupted with thy beauty: because of the multitude of thy sins I have cast thee to the ground, I have caused thee to be put to open shame before kings.
18 Because of the multitude of thy sins and the iniquities of thy merchandise, I have profaned thy sacred things; and I will bring fire out of the midst of thee, this shall devour thee; and I will make thee ashes upon thy land before all that see thee.
19 And all that know thee among the nations shall groan over thee: thou art gone to destruction, and thou shalt not exist any more.
