'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

3039. 'He will send His angel before you' means Divine Providence. This is clear from the meaning of 'angel' in the Word as the Lord, though which aspect of the Lord it is appears from the train of thought, as dealt with in 1925. The aspect meant here is clearly Divine Providence. The reason why the Lord is meant in the Word by 'angels' is that everything spoken in the Word through the Prophets and all others, though dictated by angels, is received from the Lord, that is, it is the Lord's Own. Angels in heaven also acknowledge and perceive that nothing good or true originates in themselves but in the Lord; indeed so great is their acknowledgement and perception that they turn away from everything that suggests any other idea. This explains why 'angels', that is to say, good ones, are used to mean the Lord, though which aspect of the Lord it is appears from the train of thought.
