9373. Come up unto Jehovah. That this signifies conjunction with the Lord, is evident from the signification of “coming up,” as being to be raised toward interior things (see n. 3084, 4539, 4969, 5406, 5817, 6007), consequently also to be conjoined (n. 8760). That it denotes conjunction with the Lord, is because by “Jehovah” in the Word is meant the the Lord, (n. 1343, 1736, 1793, 2004, 2005, 2018, 2025, 2921, 3023, 3035, 5663, 6280, 6303, 6905, 8274, 8864, 9315). A secret which also lies hidden in the internal sense of these words, is that the sons of Jacob, over whom Moses was the head, were not called and chosen; but they themselves insisted that Divine worship should be instituted among them (according to wh at has been said in n. 4290, 4293); and therefore it is here said, “and He said unto Moses, Come up unto Jehovah,” as if not Jehovah, but another, had said that he should come up. For the same reason in what follows it is said that “the people should not go up” (verse 2); and that “Jehovah sent not His hand unto the sons of Israel who were set apart” (verse 11); and that “the appearance of the glory of Jehovah was like devouring fire on the top of the mountain in the eyes of the sons of Israel” (verse 17); and lastly that Moses, being called the seventh day, “entered into the midst of the cloud.” For by “the cloud” is meant the Word in the letter (n. 5922, 6343, 6752, 6832, 8106, 8443, 8781); and with the sons of Jacob the Word was separated from its internal sense, because they were in external worship without internal, as can be clearly seen from the fact that now, as before, they said, “all the words which Jehovah hath spoken we will do” (verse 3); and yet scarcely forty days afterward they worshiped a golden calf instead of Jehovah; which shows that this was hidden in their hearts while they were saying with their lips that they would serve Jehovah alone. But nevertheless those who are meant by “the called and the chosen” are those who are in internal worship, and who from internal worship are in external; that is, those who are in love to and faith in the Lord, and from this in love toward the neighbor.

This term refers to good things we do for other people. Such actions are done sincerely without any expectations for something in return. This last part is a key component of the concept of good works as intentions really determine everything (See Arcana Coelestia 6393). The Lord flows into good works, and the person doing them moves to a higher spiritual state.

Good works are connected to faith. A life of faith requires one to perform good works. Otherwise, a person is not actually living a life of religion. This is shown at the very beginning of Doctrine of Life:

“Religion is all about how we live, and the religious way to live is to do good.”

Of course, there is a bit more nuance to the matter (e.g. what's really good? who is it good for? over what time range?) but that’s what is all comes down to – doing good.

4865. And thought her to be a harlot. That this signifies no otherwise than as falsity, is evident from the signification of a “harlot,” as being falsity (n. 2466, 2729, 3399); and thus it means that the Jewish nation from its religiosity regards the internal of the church no otherwise than as falsity. That a “harlot” denotes falsity, is because marriage represents the heavenly marriage, which is of good and truth, the husband representing good, and the wife truth; and hence sons represent truths, and daughters goods; and son-in-law and daughter-in-law, father-in-law and mother-in-law, and the several relationships, according to their degrees, represent those things which are of the heavenly marriage. Therefore adulteries and harlotries, being opposite, signify evil and falsity; and they are opposite in reality, for those who spend their lives in adultery and harlotry care nothing for good and truth. The reason is, that genuine conjugial love descends from the heavenly marriage, that is, from the marriage of good and truth; but adulteries and harlotries arise from the conjunction of evil and falsity, which is from hell (see n. 2727-2759).

[2] That the Jewish nation regarded, and also at this day regards, the internal things of the church no otherwise than as falsities, is what is signified by Judah’s regarding Tamar his daughter-in-law no otherwise than as a harlot, and by his conjoining himself with her as with a harlot. By this origin of that nation is represented the origin and quality of their religiosity. That this nation regards the internal of the church as a harlot, or as falsity, is very evident. As for example, if anyone tells them that it is an internal of the church that the Messiah-whose coming is predicted in the prophetic parts of the Word and whom they therefore expect-is the Lord, they utterly reject it as false. If anyone tells them that it is an internal of the church that the Messiah’s kingdom is not worldly and temporal, but heavenly and eternal, they pronounce this also to be false. If anyone tells them that the rituals of their church represented the Messiah and His heavenly kingdom, they do not know what this means.

[3] If anyone tells them that the internal of the church is the good of charity, and the truth of faith in doctrine and at the same time in life, they regard it as no otherwise than false. And so in all other instances. Nay, at the mere suggestion of the church having an internal, they laugh stupidly. The reason is that they are solely in externals, and indeed in the lowest of externals, namely, the love of earthly things; for they above all other men are in avarice, which is altogether earthly. Such men cannot possibly regard the interior things of the church in any other way; for they are more remote from heavenly light than the rest of mankind, thus above all others are in thick darkness.
