'Wilderness' signifies something with little life in it, as described in the internal sense in Luke 1:80 'Wilderness' signifies somewhere there is no good because there is no truth. 'Wilderness,' as in Jeremiah 23:10, signifies the Word when it is adulterated.

6831. 'And the angel of Jehovah appeared to him' means the Lord's Divine Human. This is clear from the meaning of 'the angel of Jehovah' as the Lord's Divine Human, dealt with in 6280. The reason why the Divine Human is called 'the angel of Jehovah' is that before the Lord's Coming, whenever Jehovah passed through heaven He appeared in human form, as an angel; for heaven as a whole resembles one entire human being, called the Grand Man, which has been the subject at the ends of quite a number of chapters. When therefore the Divine Himself passed through heaven He appeared in human form, as an angel, before the eyes of those to whom He spoke. This was Jehovah's Divine Human before the Lord's Coming. And the Lord's Human, having been made Divine, is also Jehovah's Divine Human, for the Lord is Jehovah Himself in the Divine Human. The fact that the Lord's Divine Human is called 'the angel', may be seen in 6280. It is also clear from a number of places in the New Testament where the Lord says that He is The sent from the Father; 'being sent' means going forth, and in the Hebrew language 'the sent' is used to mean an angel. For places where the Lord says He is 'the sent', see Matthew 10:40; 15:24; Mark 9:37; Luke 4:43; 9:48; 10:16; John 3:17, 34; 4:34; 5:23-24, 36-38; 6:29, 39-40, 44, 57; 7:16, 18, 28-29; 8:16, 18, 29, 42; 9:4; 10:36; 11:41-42; 12:44-45, 49; 13:20; 14:24; 16:5, 7; 17:3, 8, 18, 21, 23, 25.
