509. Verse 8. And the second angel sounded, signifies influx out of heaven, and the second consequent change with the evil, as is evident from what has been said and shown above n. 502.

Catching" is used in a variety of ways in the Bible, both positive and negative. Thieves get caught; the Egyptians caught up with the Children of Israel at the Red Sea; a ram got caught in a thicket for Abraham to sacrifice instead of sacrificing Isaac.

In a more positive sense, Jesus caught Peter when Peter was walking on water and started to sink, and the baby in Revelation was caught up to heaven before the dragon could eat him.

In all these cases, both positive and negative, being caught represents a communication and even conjunction between spiritual states. Sometimes it means higher states get ensnared in the falsity and evil of lower states; sometimes it means higher states reach out to and elevate lower ones by sharing deeper truths and describing more exquisite desires for good.
