حِزْقِيَال 10:1

ثُمَّ نَظَرْتُ وَإِذَا عَلَى ٱلْمُقَبَّبِ ٱلَّذِي عَلَى رَأْسِ ٱلْكَرُوبِيمِ شَيْءٌ كَحَجَرِ ٱلْعَقِيقِ ٱلْأَزْرَقِ، كَمَنْظَرِ شِبْهِ عَرْشٍ.

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.
