Revelation 4:6

Before the throne was something like a sea of glass, similar to crystal. In the midst of the throne, and around the throne were four living creatures full of eyes before and behind.
Ezekiel 10:4-5

The glory of Yahweh mounted up from the cherub, [and stood] over the threshold of the house; and the house was filled with the cloud, and the court was full of the brightness of Yahweh's glory.

The sound of the wings of the cherubim was heard even to the outer court, as the voice of God Almighty when he speaks.
