Ezekiel 10:9 ASV

⁷  And the cherub stretched forth his hand from between the cherubim unto the fire that was between the cherubim, and took 'thereof', and put it into the hands of him that was clothed in linen, who took it and went out.

⁸  And there appeared in the cherubim the form of a man's hand under their wings.

⁹  And I looked, and behold, four wheels beside the cherubim, one wheel beside one cherub, and another wheel beside another cherub; and the appearance of the wheels was like unto a beryl stone.

¹⁰  And as for their appearance, they four had one likeness, as if a wheel have been within a wheel.

¹¹  When they went, they went in their four directions: they turned not as they went, but to the place whither the head looked they followed it; they turned not as they went.
