Ezekiel 1:22,23

‘And over the head of the living creature there was the likeness of a firm level surface, like the colour of awesome ice stretched out over above their heads. And under the firm level surface were their wings, straight, the one towards the other. Every one had two which covered on this side, and every one had two which covered on that side, their bodies.'

Above the cherubim was the platform on which the throne of God was set (Ezekiel 1:26) and it was held up by their wings. But note the emphasis again on the fact that they had two wings with which to cover their bodies. Their task was a sacred task, and they must not presume or come ‘naked' before the Holy One. The platform was like the colour of ‘awesome ice', another attempt to stress the otherworldliness and divine splendour of the chariot.
