'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.

2160. Verse 4 Let now a little water be taken, and [all of you] wash your feet, and recline under the tree.

'Let now a little water be taken' means that they were to draw near and bring themselves down from Divine things nearer to His intellectual concepts. 'And wash your feet' means that they were to take on something natural so that during the state He was then passing through His perception might be improved. 'And recline under the tree' means towards the perception of the state through which He was passing, 'tree' meaning perception.
