Arcana Coelestia # 5668
5668. 'And gave them water' means a general influx of truth from the internal. This is clear from the meaning of 'water' as truth, 2702, 3058, 3414, 4976, in this case truth in general. This is why 'giving water' means a general influx of truth; and the reason it comes from the internal is that this took place in Joseph's house, 5667. A general influx of truth is enlightenment that makes it possible for truth to be discerned and understood. This enlightenment is provided by the light of heaven which flows from the Lord, a light which is nothing else than Divine Truth, 2776, 3138, 3167, 3195, 3222, 3339, 3485, 3636, 3643, 3993, 4302, 4413, 4415, 5400.

3339. In the next life those forms of light, and also those forms of warmth, manifest themselves visually. Angels live within the light of heaven and also within the warmth that has been spoken of. From that light they receive intelligence, and from that warmth the affection for good. Indeed the forms of light seen with their external sight have their origin in the Lord's Divine wisdom, and the forms of warmth which are also felt by them have their origin in the Lord's Divine love. To the extent therefore that spirits and angels possess intelligence in truth and affection for good they are closer to the Lord.
