Yechezkel 10:7-9

Orthodox Jewish Bible

⁷ And one Keruv stretched forth his yad from between the Keruvim unto the eish that was between the Keruvim, and took thereof, and put it into the hands of him that was clothed with linen: who took it, and went out.

⁸ And Keruvim appeared to have the tavnit (form) of a yad adam under their kenafayim (wings).

⁹ And when I looked, hinei, the four Ofanim (wheels) by the Keruvim, one Ofan beside one Keruv, and another Ofan beside another Keruv: and the appearance of the Ofanim was like the color of tarshish even (stone).
