9515. Covering with their wings over the propitiatory [mercy seat]. That this signifies the spiritual things that cover (or protect), is evident from the signification of “covering over the propitiatory [mercy seat]” as being to cover the good through which there is an approach to the Lord; and from the signification of “wings,” as being the truths of faith, or things spiritual (of which just above, n. 9514, and n. 8764). Spiritual things are said to “cover,” because the celestial, which is the good of love, is presented in heaven as naked; but as clothed, by means of spiritual things, which are the truths of faith.
