Fear not, as in Genesis 20:8, signifies aversion. To fear signifies to disbelieve or not to have faith and love, as in Isaiah 43:1, 5; 44:8; Mark 5:36; Luke 1:73, 75; 4:40; 8:49; 12:7, 32.

Fear not, as in Revelation 1:17; Daniel 10:5, 12; Matthew 17:5, 7; 28:10, etc., signifies resuscitation to life, and at the same time adoration from the most profound humiliation.

512. And they heard a loud voice from heaven saying to them, "Come up here." (11:12) This symbolizes the two essential elements of the New Church raised by the Lord into heaven, where they originate and where they remain, and where they are protected.

The loud voice from heaven symbolizes a command from the Lord, for a voice from heaven has no other origin. The command to come up here symbolizes the elevation of the two essential elements into heaven, where they originate and where they remain, and where they are protected.
