9207. And your sons shall be orphans. That this signifies that then at the same time truths will perish, is evident from the signification of "orphans," as being those who are in truth and not yet in good, and nevertheless long for good (see n. 9199), here those who are in truth but do not long for good, thus those with whom truths are perishing; for it is said of the evil, whose sons shall become orphans. That truths perish with those who do not long for good, is plain from what was said just above (n. 9206) about the conjunction of good and truth. With regard to this conjunction it is to be said further, that truths which are conjoined with good always have within them a longing to do what is good, and at the same time, to thereby conjoin themselves more closely with good; or, what is the same, those who are in truths always long to do what is good, and thus to conjoin good with their truths; and therefore those who believe themselves to be in truths and do not long to do what is good, are not in truths; that is, they are not in the faith of these truths, howsoever they may suppose themselves to be so.
 This is described by the Lord by "salt," where He says in Matthew:
Ye are the salt of the earth; but if the salt has lost its savor, wherewith shall it be salted? It is thenceforth good for nothing, but to be cast out and trodden under foot of men (Matt. 5:13);
these words the Lord says to the disciples and to the people. By "the salt of the earth" is meant the truth of the church which longs for good; by "the salt that has lost its savor" is meant truth without any longing for good; that such truth is profitable for nothing is described by "the salt that has lost its savor being thenceforth good for nothing, but to be cast out and trodden under foot." To long for good is to long to do what is good, and in this way to be conjoined with good.
 So in Mark:
Everyone shall be salted with fire, and every sacrifice shall be salted with salt. Salt is good; but if the salt have lost its saltiness, wherewith will ye season it? Have salt in yourselves, and cherish peace one with another (Mark 9:49-50);
"to be salted with fire" denotes the longing of good for truth; and "to be salted with salt" denotes the longing of truth for good; "salt that has lost its saltiness" denotes truth without any longing for good; "to have salt in oneself" denotes to have this longing.
 So in Luke:
Every one of you who does not renounce all that he has cannot be My disciple. Salt is good; but if the salt have lost its savor, wherewith shall it be seasoned? It is fit neither for the land, nor for the dunghill: they cast it out (Luke 14:33-35);
here in like manner "salt" denotes truth longing for good; and "salt that has lost its savor," truth which is without any longing for good; "it is fit neither for the land nor for the dunghill" denotes that it does not conduce to any use, either good or evil. Those who are in such truth are those who are called "lukewarm," as is plain from the words which precede, that "no one can be a disciple of the Lord who does not renounce all that he has," that is, who does not love the Lord above all things; for those who love the Lord, and likewise themselves, in an equal degree, are those who are called "lukewarm," and who are not fit for either a good use or an evil use.
 In Moses:
Every offering of thy meat-offering shall be salted with salt; neither shalt thou suffer the salt of the covenant of thy God to cease upon thy meat-offering; upon every offering thou shalt offer salt (Lev. 2:13);
that "in every offering there should be salt" signified that the longing of truth for good, and of good for truth, should be in all worship. Consequently this "salt" is called "the salt of the covenant of God," for "a covenant" denotes conjunction (n. 665, 666, 1023, 1038, 1864, 1996, 2003, 2021, 2037, 6804, 8767, 8778), and "salt" the longing for conjunction.
 When the one longs to be reciprocally conjoined with the other, that is, good with truth and truth with good, they then mutually regard each other; but when truth sunders itself from good, then each turns away from the other, and looks backward, or behind itself. This is signified by Lot's wife becoming a pillar of salt, as in Luke:
Whosoever shall be upon the house, and his vessels in the house, let him not go down to take them away; and whosoever is in the field, let him likewise not turn back to the things behind him. Remember Lot's wife (Luke 17:31-32).
(That this is "to look behind" one's self, or "backward," see n. 3652, 5895, 5897, 7857, 7923, 8505, 8506, 8510, 8516).
 That "salt" signifies the longing of truth, is because salt renders the earth fertile, and makes food palatable, and because there is in salt something both fiery and at the same time conjunctive; as there is in truth an ardent longing for good and at the same time for conjunction. A "pillar of salt" denotes disjunction from truth; for in the opposite sense "salt" signifies the destruction and vastation of truth (Zeph. 2:9; Ezek. 47:11; Jer. 17:6; Ps. 107:33, 34; Deut. 29:23; Judges 9:45; and 2 Kings 2:19-22). These things have been adduced in order that it may be known what is meant by the longing of truth for good, and the longing of good for truth, which are signified by "an orphan," and "a widow."
