51. Having in His right hand seven stars. (1:16) This symbolizes all concepts of goodness and truth in the Word, which exist therefore in angels in heaven and in people in the church.

When angels are below the heavens, a great number of what look like little stars appear around them, and likewise around spirits who, when they lived in the world, acquired concepts of goodness and truth for themselves from the Word, or truths of life and doctrine. These little stars appear fixed, however, in the case of those who possess genuine truths from the Word, but wandering in the case of those who possess falsified truths.

(Regarding these little stars, and the stars appearing in the sky there, I could relate marvelous things, but that is not the subject of this work.)

It is apparent from this that stars symbolize concepts of goodness and truth from the Word.

The Son of Man's having them in His right hand means, symbolically, that they come from the Lord alone through the Word. Seven symbolically means all, as may be seen in no. 10 above.

[2] That stars symbolize concepts of goodness and truth from the Word may be seen also from the following passages:

(I will) turn the earth into a wasteland... ...the stars of heaven and their constellations will not give their light. (Isaiah 13:9-10)

The earth that will be turned into a wasteland is the church, in which, having been laid waste, concepts of goodness and truth in the Word are not seen.

When I put out your light, I will cover the heavens... All the bright lights of the heavens I will make dark over you, and bring darkness upon your land. (Ezekiel 32:7-8)

Darkness upon the land is the darkness of falsities in the church.

The sun and moon grow dark, and the stars diminish their brightness. (Joel 2:10; 3:15)

...after the tribulation of those days the sun will be darkened, the moon will not give its light, and the stars will fall from heaven... (Matthew 24:29, cf. Mark 13:24)

The stars of heaven fell to the earth, as a fig tree drops its late figs... (Revelation 6:13)

...a star (fell) from heaven to the earth. (Revelation 9:1)

Stars falling from heaven do not mean stars, but concepts of goodness and truth perishing.

[3] This is still more apparent from the statement that a dragon swept down a third of the stars from heaven, in Revelation 12:4, and the statement that a he-goat cast down some of the stars and trampled them, in Daniel 8:8-11. That is why the next verse in Daniel goes on to say that it cast truth to the ground (Daniel 8:12).

Stars also symbolize concepts of goodness and truth in the following passages:

(Jehovah) counts... the stars; He gives all of them names. (Psalms 147:4)

Praise (Jehovah), all you stars of light! (Psalms 148:3)

The stars from their courses fought... (Judges 5:20)

From this it is apparent what is meant by the following statement in Daniel:

The intelligent shall shine like the brightness of the firmament, ...those turning many to righteousness, like the stars forever and ever. (Daniel 12:3)

The intelligent are people concerned with truths, and those turning many to righteousness are those concerned with goodness.

A "house" is essentially a container -- for a person, a family, several families or even a large group with shared interests (think of the term "houses of worship.") In the Bible, a "house" is also a container, but for spiritual things rather than natural things. In various uses a "house" can represent part of the mind, the whole mind, a whole person or even a church. The other nuance to the word "house" is that it is generally used in regards to our affections and desires rather than our thoughts and principles. This makes sense; we tend to engage our thoughts and rationality when we are out in the world doing our work, but when we are inside our houses we are driven most by love for our families and the desire to be good to those we love. So "house" tends to represent the things we want and care about -- which are ultimately the things that define us.
