'A partridge,' as in Jeremiah 17:11, signifies people who learn many things from the Word and from the doctrine of the church, but not for the sake of uses of life. 'To hatch eggs,' or 'to prepare,' is to perform uses, which is living, and so being reformed.

(Reference: Apocalypse Explained 236, 721)

In Revelation 4:7, a face like a man signifies affection of truth, and, more interiorly, wisdom. (Apocalypse Revealed 243, Apocalypse Explained 280)
