Arcana Coelestia # 60
60. Verse 31 And God saw everything that He had made, and behold, it was very good. And there was evening, and there was morning, a sixth day.
This verse says 'very good', whereas previous verses merely said 'good', for now the things of faith make one with those of love. A marriage has accordingly taken place between spiritual and celestial things.
Fowl
Fowl signify spiritual truth; a bird, natural truth; and a winged thing, sensual truth. Fowl of heaven, as in Hosea 2:18, signify the affections of truth; and reptiles of the earth, the affection of the knowledges of truth and good. Fowl signify thoughts, and all that creeps on the ground, the sensual principle. Fowl signify intellectual things.
