'Wing' in the Bible

One wing of the first cherub was 7½ feet long, and the other wing was 7½ feet long. The wingspan was 15 feet from tip to tip.

Then he put the cherubim inside the inner temple. Since their wings were spread out, the first one’s wing touched one wall while the second cherub’s wing touched the other wall, and in the middle of the temple their wings were touching wing to wing.
