Книга пророка Иезекииля 10:1

И видел я, и вот на своде, который над главами Херувимов, как бы камень сапфир, как бы нечто, похожее на престол, видимо было над ними.

Then I looked, and, behold, in the firmament that was above the head of the cherubims there appeared over them as it were a sapphire stone, as the appearance of the likeness of a throne.
