8349. And they could not drink the waters for bitterness, because they were bitter. That this signifies that truths appeared to them undelightful, because devoid of the affection of good, is evident from the signification of "to drink the waters," as being to receive truths and apply them under good (of which n. 3069, 5709); from the signification of "waters," as being truths (of which just above, n. 8347); and from the signification of "bitter," as being what is undelightful (n. 7854). Hence it is evident that by "they could not drink the waters for bitterness, because they were bitter," is signified that truths appeared to them undelightful: that it denotes because devoid of the affection of good, is because all the delight of truth comes forth from good. That the affection of truth derives its origin from good is because good loves truth, and truth loves good, for these two are conjoined as in a marriage. It is known that everyone desires to be instructed in those things which he loves and has as the end. He who loves good, that is, who wills from the heart to worship God and to benefit his neighbor, loves to be instructed in those things which lead thereto, consequently in truths; from which it can be seen that all the affection of truth is from good.
 There are indeed some who live in an evil manner, and yet desire to be instructed in truths; but with these there is no affection of truth, but only the affection of confirming the doctrinal things of the church for the sake of self-glory, that is, for the sake of reputation, honors, or gain. The genuine affection of truth is to wish to know what is true for the sake of the life in the world, and for the sake of life eternal. These come into temptation when truths begin to fail them, and more when the truths which they know appear undelightful. This temptation derives its origin from the fact that the communication with good has been intercepted. This communication is intercepted as soon as the man comes into his own, for he thus sinks down into the evil of the love of self, or of the world. When he emerges from this state, truths become delightful. This is meant in what follows by the bitter waters being healed by means of the wood cast into them, for by "wood" is signified good.
