496. These have power to shut heaven, so that no rain falls in the days of their prophecy. (11:6) This symbolically means that people who turn away from these two essential elements of the New Church cannot receive any truth from heaven.

Heaven here means the angelic heaven. Thus the rain symbolizes truth for the church from there. Consequently to close heaven so that no rain falls means, symbolically, that people cannot receive any truth for the church from heaven. Truth for the church from heaven is doctrinal truth from the Word.

We are told that the two witnesses have the power to shut heaven, but as in no. 494 above, the meaning here is not that they have that power, but that people who turn away from the two essential elements of the New Church close heaven to themselves, because they continue to be caught up in their falsities.

That rain symbolizes Divine truth from heaven is clear from the following passages:

My doctrine shall drop as the rain, My word shall fall as the dew... (Deuteronomy 32:2)

(If) you... serve other gods..., (Jehovah will) shut up heaven so that there be no rain... (Deuteronomy 11:16-17, see also 11:11, 11:14)

I will lay waste (My vineyard).... I will also command the clouds that they rain no rain on it. (Isaiah 5:6)

The showers have been withheld, and there has been no late rain. Yet you continue to have a harlot's forehead... (Jeremiah 3:3)

For as the rain comes down... from heaven..., so shall My word (go) forth from My mouth. (Isaiah 55:10-11)

Rejoice then, you children of Zion, and be glad in Jehovah... For He has given you seasonable rain in righteousness. (Joel 2:23)

You have caused to drop, O God, a kindly rain... (Psalms 68:9)

He shall come down like rain upon the grass of the meadow... In His days the righteous shall flourish... (Psalms 72:6-7)

He will come to us as rain, as the late... rain waters the earth. (Hosea 6:3)

...my word shall rain down on them, and they will wait for me as for the rain, and they will open their mouth for the late rain. (Job 29:22-23)

Son of man, say...: "You are a land that is not cleansed, which will have no rain in the day of wrath. There is a conspiracy of her prophets in her midst... (Ezekiel 22:24-25)

And so on elsewhere, as in Isaiah 30:23; Jeremiah 5:24; 10:12-13; 14:3-4; 51:16.

A flooding rain stands for the destruction of truth in Ezekiel 13:11, 13-14; 38:22. For temptation or trial in Matthew 7:24-27.

7710. 'Stretch out your hand towards heaven' means exercising the power of God's truth in heaven. This is clear from the meaning of 'stretching out the hand' as an exercising of power, dealt with above in 7673; from the representation of Moses, the one who was told to 'stretch out his hand', as God's truth, dealt with in 6723, 6752, 7010, 7014, 7382; and from the meaning of 'heaven' as the angelic heaven. How it is that exercising the power of God's truth in heaven could bring about the new state among the molesting ones that is meant by 'thick darkness' is clear from what has been shown in 7643, 7679. There it has been shown that the Lord is continually rearranging heaven, and that He endows those in heaven, and newcomers, with celestial and spiritual good. This continual rearranging causes the vastation which the evil undergo in stages; for after rearrangement that good flows from a more immediate position towards the evil who are governed by the opposite of such good. (The inflow from God continues onwards right into what is opposed to it and in so doing keeps the hells bound and chained.) And since the evil turn all good into evil, they turn into greater evil the good that flows in from a more immediate position. The more they do so, the stronger is their resistance to what is good and true, that is, the fiercer is their molestation of it. So it is that the vastation they undergo proceeds in stages, till at length they are cast into hell, which is the final stage of it. From all this one may see that what emanates from the Lord is nothing but good, and that He does not lay waste the evil, still less cast them into hell, but that they themselves cause it to happen.
