259. Verse 1. After these things I saw, and, behold, a door opened in heaven; and the first voice which I heard, as it were of a trumpet speaking with me, saying, Come up hither, and I will show thee things which must come to pass hereafter.

"After these things I saw," signifies the understanding enlightened; "and, behold, a door opened in heaven," signifies the arcana of heaven revealed; "and the first voice which I heard" signifies revelation now of things to come; "as it were of a trumpet speaking with me," signifies what is clear and manifest; "saying, Come up hither," signifies elevation of mind, and attention: "and I will show thee things which must come to pass hereafter," signifies instruction concerning those things that will exist in the last time of the church.

'Waters,' 'rivers,' and 'depths,' as in Psalm 78:15-16, signify truths from the Lord.
