Name known only to Himself
In Revelation 19:12, this symbolically means that what the Word is like in its spiritual and celestial senses, no one sees but the Lord, and the person to whom He reveals it. (Apocalypse Revealed 824)
Arcana Coelestia #4866
4866. 'Because she had covered her face' means that interior things were hidden from them. This is clear from the representation of 'Tamar' as the representative Church, dealt with in 4829, 4831; from the meaning of 'covering' as being hidden; and from the meaning of 'the face' as internal things, dealt with in 358, 1999, 2434, 3527, 3573, 4066, 4326, 4796-4799. From this it is evident that 'she covered her face' means that the interior things of the Church were hidden from them. Regarding these, see above in 4859, 4865.
