以西结书 1:13

至于四活物的形象，就如烧着火炭的形状，又如火把的形状。火在四活物中间上去下来，这火有光辉，从火中发出闪电。

As for the likeness of the living creatures, their appearance was like burning coals of fire, and like the appearance of lamps: it went up and down among the living creatures; and the fire was bright, and out of the fire went forth lightning.
