Ezekiel 1:11-13

11 Thus [were] their faces; and their wings [were] stretched upward; two [wings] of each one [were] joined one to another, and two covered their bodies.

12 And they went each one straight forward in the direction they were facing: wherever the Spirit directed them to go, they went; [and] they did not return when they went.

13 As for the likeness of the living creatures, their appearance [was] like burning coals of fire [and] like the appearance of [lit] torches; the [fire] went up and down among the living creatures and the brightness of the fire; and out of the fire went forth lightning.
