6777. And they filled the troughs. That this signifies that from this they enriched the doctrine of charity, is evident from the signification of "filling from a well," as being to enrich from this, or from the Word; and from the signification of a "trough," as being the doctrine of charity. That a "trough" or "basin" is the doctrine of charity, is because it is a trough of wood into which water is drawn from a well to give drink to flocks; for what is of "wood" in the internal sense signifies the good of charity (n. 3720); "to draw" signifies to be instructed (n. 3058, 3071); the "water" which is drawn, signifies the truth of faith (n. 2702, 3058, 4976, 5668); the "well" from which it is drawn signifies the Word (n. 2702, 3424, 6774); and "to give drink to the flocks" signifies to instruct in good from the Word (n. 3772). From all this it is evident that a "trough" is the doctrine of charity.
