The number "two" has two different meanings in the Bible. In most cases "two" indicates a joining together or unification. This is easy to see if we consider the conflicts we tend to have between our "hearts" and our "heads" -- between what we want and what we know. Our "hearts" tell us that we want pie with ice cream for dinner; our "heads" tell us we should have grilled chicken and salad. If we can bring those two together and actually want what's good for us, we'll be pretty happy. We're built that way -- with our emotions balanced against our intellect -- because the Lord is built that way. His essence is love itself, or Divine Love, the source of all caring, emotion and energy. It is expressed as Divine Wisdom, which gives form to that love and puts it to work, and is the source of all knowledge and reasoning. In His case the two aspects are always in conjunction, always in harmony. It's easy also to see how that duality is reflected throughout creation: plants and animals, food and drink, silver and gold. Most importantly, it's reflected in the two genders, with women representing love and men representing wisdom. That's the underlying reason why conjunction in marriage is such a holy thing. So when "two" is used in the Bible to indicate some sort of pairing or unity, it means a joining together. In rare cases, however, "two" is used more purely as a number. In these cases it stands for a profane or unholy state that comes before a holy one. This is because "three" represents a state of holiness and completion (Jesus, for instance, rose from the tomb on the third day), and "two" represents the state just before it.

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.
