Yechezkel 1:14-16

Orthodox Jewish Bible

¹⁴ And the Chayos ran and returned as the appearance of bazak (a flash of lightning).

¹⁵ Now as I beheld the Chayos, hinei there was one Ofan ba’aretz etzel the Chayos, with its four panim.

¹⁶ The appearance of the Ofanim and their making was like unto the color of tarshish; and they four had one demut; and their appearance and their making was as it were an Ofan within an Ofan.
