'The tent,' as in Exodus 26:14, represented the three heavens, and so the celestial and spiritual parts of the Lord's kingdom.

A 'Tent' signifies the celestial and holy aspects of love, because in ancient times people performed holy worship in their tents.

When they began to profane tents with profane worship, the tabernacle was built, and later the temple. This is why the tabernacle and the temple signify the same as 'tent.'

A holy man was therefore called a tent, a tabernacle, and a temple of the Lord. In the highest sense, the Lord regarding His human essence, is a tent, a tabernacle, and a temple. Every celestial person is called these things, and so every thing celestial and holy has acquired these names.

This is why the feast of tabernacles was instituted, when they gathered in the produce of the earth, as a remembrance of those earlier holy times, and it was ordained, that at this feast they should live in tabernacles, like the most ancient people, as in Leviticus 23:39-44, Deuteronomy 16:13, and Hosea 12:9.

3459. 'And swore, a man to his brother' means confirmation with those who do the good of truth. This is clear from the meaning of 'swearing' or of 'an oath' as confirmation, dealt with in 2842, 3037, 3375, and from the meaning of 'a man to his brother' as the good of truth, or what amounts to the same, one who is governed by that truth - 'man' meaning truth, see 265, 749, 1007, 3134, 3309, and 'brother' good, 2360. For what the good of truth is, see 3295, 3332. This good occurs with those represented here by Abimelech or by the Philistines, of whom Abimelech was the king, that is to say, those who make faith the essential thing of the Church and rank it above charity. No other good exists with such persons than the good of truth. Indeed they extract and draw out of the Word nothing else than references to faith and so to truth. They hardly notice references to good and so to life, and as a consequence they become more firmly convinced by matters of doctrine concerning faith and not by any concerning charity. When they do perform a good action it is one prescribed by matters of doctrine concerning faith. Good prescribed by these is called the good of truth.

[2] The Lord does indeed join Himself to those with whom this good exists, but not in the same way as He does to those who do the good of charity, for love and charity constitute spiritual conjunction, but not so faith except through love and charity. It is for this reason that the words used are not 'they made a covenant with Isaac' but 'they swore, a man to his brother'; for 'a covenant' has reference to good, which is the good of love and charity, whereas 'an oath' has reference to truth, which is the truth of faith, 3375. Also 'dwelling together' meant by 'a feast', 3456, is used in reference to those who do the good of truth. From people such as these in the next life I have been given to know that they have been separated from those who do the good of charity; for the latter are joined more nearly to the Lord than the former, since the former's good is so to speak hard and inflexible, and not communicable, and so is not in heaven but on the threshold of heaven.
