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.

3101. 'So as to know whether Jehovah had prospered his way or not' means regarding Divine Truth, as to what sort it was. This is clear from the meaning of 'way' as truth, dealt with in 627, 2333. The Divine nature of that truth is meant by the words 'whether Jehovah had prospered' which amounts to the same as, whether it was from Jehovah, that is, from the Divine. Accordingly what sort of truth is meant, for the truths that are summoned from the natural man into the rational man are not all received, only those that accord with the good there, and on being sown and implanted in this way act as one with that good. The rest, even though they may have appeared as truths prior to being raised up, are nevertheless not received because they are not acknowledged. Good is that which acknowledges its own truth, and truth that which acknowledges its own good. That it was an acknowledgement of what sort of truth it was, and that thus this truth was received, is also evident from what follows next.
