The first altar mentioned in the Word was the one built by Noah after he came out of the ark, after being saved from the great flood. On that altar, he sacrificed clean animals to the Lord.

Mountains represent the Lord because of their height; we need to raise our thoughts above worldly things when "talking" with the Lord. An altar is a small artificial mountain. When it's used in worship, it can call to mind this raising of thought. The fire and smoke that rise from an altar are symbolically being sent to the Lord.

Most altars were made from unhewn stones. Stones represent truths. Unhewn stones - ones that have not been shaped by men - represent truths from the Word, truths that have not been adulterated.

The clean beasts to be sacrificed represent good things, charitable acts done because they are right. The clean birds represent thoughts about doctrine and actions, and about what is right. Presenting these things is an acknowledgment that we have them from the Lord, and a giving thanks to Him for them.

In the Israelitish Tabernacle, the altar of burnt offering represented the acknowledgment of good and the altar of incense that of truth. For this reason this larger altar, which was outside by the door, was made of brass which signifies natural good, while the altar of incense was made of gold, which signifies love to the Lord from whom comes truth.

2069. 'Kings of peoples will be from her' means truths that are the product of truths and goods joined together, meant by 'kings of peoples'. This is clear from the meaning of 'kings' as all truths in general, dealt with above in 2015, and from the meaning of 'peoples' also as truths, in general all things that are spiritual. For 'kings' are spoken of in reference to peoples, and not so much in reference to nations except when the nations mean evils, dealt with in 1259, 1260. In the prophetical part of the Word kings and peoples are mentioned many times, but nowhere are they used to mean kings and peoples, for at no point are kings and peoples the subject in the Word proper, which is the internal sense, but the celestial and spiritual things comprising the Lord's kingdom, and so goods and truths. The sense of the letter expresses itself by means of perceivable objects, as anyone does with words, merely to enable understanding.

[2] Since the subject here is Sarah and the promise that 'kings of peoples will be from her', and since 'Sarah' means Divine Truth which was the Lord's, 'kings of peoples' clearly means truths that are the product of truths and goods joined together, which are all the truths of the internal Church, that is, the interior truths of faith. Because these truths come from the Lord, they are frequently called 'kings' in the Word, and also 'a king's sons', as shown above in 2015.

[3] Anyone may see that some internal Divine matter lies concealed in the words that 'kings of peoples will be from her'. For the subject in this verse is Isaac, of whom it is said, 'I will bless him, and he will become nations', but of Sarah that 'kings of peoples will be from her'. Almost the same was also said of Abraham in verse 6 above, that 'kings will go out of him'; but it did not say as it does of Sarah, 'kings of peoples'. The arcanum within this lies too deep to allow it to be uncovered and described in a few words. From the representation and meaning of 'Abraham' as Divine Good and from the representation and meaning of 'Sarah' as Divine Truth the arcanum is to some extent evident, namely that from the Lord's Divine Good meant by 'Abraham' all celestial truth will come forth and have its being, and from the Lord's Divine Truth meant by 'Sarah' all spiritual truth will do so. Celestial truth is the truth which exists with celestial angels, and spiritual truth that which exists with spiritual angels. Or what amounts to the same, celestial truth was the truth which existed with members of the Most Ancient Church which came before the Flood and which was a celestial Church, spiritual truth that which existed with members of the Ancient Church which came after the Flood and was a spiritual Church. For angels, as also members of the Church, are distinguished into celestial and spiritual. That which distinguishes the celestial from the spiritual is love to the Lord, and that which distinguishes spiritual from celestial is love towards the neighbour.

[4] No more can be said about celestial truth and spiritual truth however until the difference between the celestial and the spiritual is known, or what amounts to the same, the difference between the celestial Church and the spiritual. For this see Volume One, in 202, 337, 1577; then concerning the nature of the Most Ancient Church and the nature of the Ancient Church, in 597, 607, 640, 765, 1114-1125, and in many other places. On the point that possessing love to the Lord constitutes the celestial, and possessing love towards the neighbour the spiritual, see 2023.

[5] These considerations now show what the arcanum is, namely that 'the kings who will go out of Abraham', referred to in verse 6, mean celestial truths that flow in from the Lord's Divine Good, while 'the kings of peoples who will be from Sarah', referred to in the present verse, mean spiritual truths that flow in from the Lord's Divine Truth. For the Lord's Divine Good is unable to flow in except with the celestial man since it is an influx into the will part of his mind, as was the case with the Most Ancient Church, whereas with the spiritual man the Lord's Divine Truth is flowing in since the influx is solely into the understanding part, which in him has been separated from the will part, 2053 (end). Or what amounts to the same, celestial good is flowing in with the celestial man, and spiritual good with the spiritual man. As a consequence the Lord is seen by celestial angels as the Sun, but by spiritual angels as the Moon, 1529, 1530.
