That this signifies doctrine therefrom, is evident from the signification of a “well,” as being the Word (n. 2702, 3424); and because the Word is doctrine itself, and thus all the doctrine which is of the church is from the Word, to “dig out a well” signifies doctrine therefrom, namely, from the literal sense of the Word, because this sense is here treated of. But doctrine itself from the literal sense of the Word is one only, namely, the doctrine of charity and love-of charity toward the neighbor and of love to the Lord; for this doctrine and life according to it is the whole Word, as the Lord teaches in Matthew 22:37-40.
