'Living Creatures' in the Bible

Also out of the midst thereof, the likeness of four living creatures. And this was their appearance: they had the likeness of a man.

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

And the living creatures ran and returned as the appearance of a flash of lightning.

And I looked at the living creatures, and behold, one wheel upon the earth beside the living creatures, toward their four faces.

And when the living creatures went, the wheels went beside them; and when the living creatures were lifted up from the earth, the wheels were lifted up.

And the sound of the wings of the living creatures that touched one another, And the sound of the wheels beside them, And the sound of a great rushing.
