Ezequiel 10:1

1 Olhei, e eis que, no firmamento que estava por cima da cabeça dos querubins, havia algo como uma pedra de safira e que parecia ser um trono.

1 Then looking, I saw that on the arch which was over the head of the winged ones there was seen over them what seemed like a sapphire stone, having the form of a king's seat.
