That this signifies a general influx of truth from the internal, is evident from the signification of “waters,” as being truth (see n. 2702, 3058, 3424, 4976), and indeed truth in general. Hence “giving waters” signifies a general influx of truth. That it is from the internal, is because it was in Joseph’s house (n. 5667). A general influx of truth is the enlightenment which gives the capacity of apprehending and understanding truth. This enlightenment is from the light of heaven that is from the Lord, which light is nothing else than the Divine truth (see n. 2776, 3138, 3167, 3195, 3223, 3339, 3485, 3636, 3643, 3993, 4302, 4413, 4415, 5400).

The very origin of the light is this and this alone. But the angels have light in proportion to what is celestial and spiritual with them, and the quality of this determines the quality of their light. Thus the Lord’s celestial and spiritual manifests itself before their external sight by means of light.
