3463. 'That Isaac's servants came' means rational concepts. This is clear from the meaning of 'servants' as rational concepts, and also as facts, dealt with in 2567, and from the representation of 'Isaac' as the Lord's Divine Rational, dealt with in 1893, 2066, 2072, 2083, 2630, 3012, 3194, 3210. From what has gone before it is clear what aspect of the Lord is represented here by Isaac, namely the Word as regards its internal sense. For by 'Abimelech, Ahuzzath, and Phicol' are meant matters of doctrine concerning faith which are drawn from the literal sense of the Word, like those matters of doctrine possessed by people who are called 'Philistines' in the good sense. That is, they are people who have no other matters of doctrine than those concerning faith, and yet so far as life is concerned they do what is good, though it is the good of truth. And these matters of doctrine do have a certain link with the internal sense, and so with the Lord.

[2] For people who have no other matters of doctrine than those concerning faith and yet who live according to them are linked in some way to Him, though in a remote way. It is remote for the reason that they do not know from any affection what charity towards the neighbour is, let alone love to the Lord, but only from some concept that belongs to faith. Thus they do not possess any perception of good, only a type of persuasion that that is true and accordingly good which their matters of doctrine tell them to be so. And when they are confirmed in those matters of doctrine they are just as likely to be subject to falsity as to truth, for nothing else than good can confirm a person as to what the truth is.

[3] Truth does indeed teach what good is, but it does so without perception, whereas good teaches what truth is from perception. Anyone may recognize this difference, and also the nature of it, simply from the following general command concerning charity,

All things whatever you would wish people to do to you, do so to them. Matthew 7:12.

The person who acts from this commandment does indeed do what is good to others; but he does it because it is so commanded rather than from any affection in the heart. And as often as he does that good deed he begins from a selfish motive, and also in doing such good his thoughts are of merit. But when he does not act from the commandment but from charity, that is, from affection, his actions begin in the heart, and so in freedom. And as often as he performs that act he begins from the desire itself for what is good, and so that which is a delight to him; and because in this delight he finds reward he has no thought of merit.

[4] From this one may now see what the difference is between doing good from faith and doing it from charity, and that people who do it from faith are more remote from good itself, which is the Lord, than those who do it from charity. The former cannot be easily brought to the good that flows from charity so that they may perceive it because truths are not present in them to any great extent. For no one can be brought to that good unless untruths have been rooted out first, which cannot be effected as long as untruths are so deeply rooted that a person is persuaded that they are truths.

2072. 'And laughed' means the affection for truth. This becomes clear from the origin and essential nature of laughter. In origin it is nothing other than the affection for truth or the affection for falsity, which produces the mirth and pleasure exhibited in the face by means of laughter. This shows that the essential nature of laughter is nothing else. Actually laughter is something external belonging to the body since it belongs to the face; but in the Word interior things are expressed and are-meant by exterior. Just as all interior affections of both areas of mind (animus et mens) are expressed and meant by the face; interior hearing and obedience by the ear; internal sight, which is understanding, by the eye; power and strength by the hand and arm; and so on; so is the affection for truth expressed and meant by laughter.

[2] The principal element in man's rational is truth. Also present in the rational there is the affection for good, but this affection is present within the affection for truth, as the soul within it. The affection for good present within the rational does not express itself in laughter but in a type of joy and a resulting sense of delight which does not laugh. For laughter generally entails something that is not so good. The reason truth is the principal element in the rational man is that the rational is formed by means of cognitions of truth, for there is no other possible way in which anyone can become rational. Cognitions of good are truths just as much as cognitions of truth are truths.

[3] That 'laughter' here means the affection for truth becomes clear from the fact that this verse records Abraham's having laughed, as did Sarah both before Isaac was born and after, and also from the fact that he was given the name Isaac from 'laughter', for the word 'Isaac' means laughter. The fact that Abraham laughed when he heard about Isaac is clear from the present verse, for it is actually stated that when he heard about a son by Sarah he laughed. Sarah's laughing as well before the birth of Isaac when she heard from Jehovah that she was going to give birth is referred to as follows,

When Sarah heard at the tent door Sarah laughed within herself, saying, After I have grown old, shall I have the pleasure, and my lord being an old man? And Jehovah said to Abraham, Why did Sarah laugh, saying, Shall I in truth bear now I have grown old? Sarah denied it, saying, I did not laugh; for she was afraid. And He said, No, but you did laugh. Genesis 18:12-13, 15.

Also later on after Isaac's birth,

Abraham called the name of his son Isaac (laughter). Sarah said, God has made laughter for me; everyone hearing of it will laugh at me. Genesis 21:3, 6.

Unless 'laughing' and the name Isaac, which means laughter, embodied such things these occurrences would never have been mentioned.
