Mother Queen of Heaven is mentioned in Psalm 45:9
To my understanding this is talking about Jesus / Saviour being annointed with gladness and Mother Queen of Heaven stood by him at this time it happened in Heaven.
Thy throne, O God, is for ever and ever: the sceptre of thy kingdom is a sceptre of righteousness. Thou hast loved righteousness, and hated iniquity: therefore God, thy God, has anointed thee with the oil of gladness beyond thy fellows.
Myrrh, and stacte, and cassia are exhaled from thy garments, and out of the ivory palaces, with which kings’ daughters have gladdened thee for thine honour: the Queen stood by on thy right hand, clothed in vesture wrought with gold, and arrayed in divers colours
Picture are of Songs Of Solomon
They changed the original to say Queens.
