Ezekiel 10:10 ASV

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.

¹²  And their whole body, and their backs, and their hands, and their wings, and the wheels, were full of eyes round about, 'even' the wheels that they four had.
