According to the verses in Ezekiel and its attendant commentaries, his vision consists of a chariot made of many heavenly beings driven by the "Likeness of a Man." The base structure of the chariot is composed of four beings. These beings are called the "living creatures" (Hebrew: חיות hayyot or khayyot). The bodies of the creatures are "like that of a human being", but each of them has four faces, corresponding to the four directions the chariot can go (East, South, North and West). The faces are that of a man, a lion, an ox (later changed to a cherub in Ezekiel 10:14) and an eagle. Since there are four angels and each has four faces, there are a total of sixteen faces. Each "Hayyot" angel also has four wings. Two of these wings spread across the length of the chariot and connect with the wings of the angel on the other side. This creates a sort of 'box' of wings that forms the perimeter of the chariot. With the remaining two wings, each angel covers its own body. Below, but not attached to, the feet of the "Hayyot" angels are other angels that are shaped like wheels. These wheel angels, which are described as "a wheel inside of a wheel", are called "Ophanim" אופנים (lit. wheels, cycles or ways). These wheels are not directly under the chariot but are nearby and along its perimeter. The angel with the face of the man is always on the east side and looks up at the "Likeness of a Man" that drives the chariot. The "Likeness of a Man" sits on a throne made of sapphire.
