Ezekiel 10:11

So He drove the man out; and at the east of the garden of Eden He stationed the cherubim and the flaming sword which turned every direction to guard the way to the tree of life.

And under their wings on their four sides were hands of a man. As for the faces and wings of the four of them,

The appearance of the wheels and their workmanship was like the gleam of beryl, and all four of them had the same likeness, their appearance and workmanship being as if one wheel were within another.

Whenever they went, they went in any of their four directions without turning as they went.
