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.

27. Verse 9 And God said, Let the waters under heaven be gathered together to one place, and let the dry land appear; and it was so.

Once a person knows of the existence of the internal man and of the external man, and knows that, contrary to appearance, truths and goods flow in from the internal man, or from the Lord by way of the internal into the external, then the things residing in him as cognitions of truth and good are stored away in his memory and registered among the facts there. For anything that finds its way into the memory or the external man, whether natural, spiritual, or celestial, lodges there as known fact, and from that place it is brought out by the Lord. These cognitions are 'the waters gathered together to one place' and are called 'seas'. But the external man itself is called 'the dry land' and immediately afterwards 'earth', as in the verses that follow.
