'Covering' in the Bible

That's what their faces were like. Their wings spread out above and around them, one pair overlapping another, with one pair covering themselves.

and underneath the canopy, their wings spread out straight over their heads toward each other. They each also had two wings with which they covered themselves, one wing covering its body on one side and one wing covering itself on the other side.

The cherubim lifted their wings and rose above the earth while I watched. They went out, along with their wheels, and stood at the entrance to the east gate of the LORD's Temple as the glory of Israel's God remained above, covering them.

As I continued to watch, I saw tendons growing on the bones, and muscles growing and covering them, and then skin covered the flesh from above. But the bodies weren't breathing.
