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.

3670. 'And He will give you the blessing of Abraham' means the joining of the Divine itself to the good and truth of the natural. This is clear from the meaning of 'blessing' as a joining together, dealt with above in 3660, 3667, and from the representation of 'Abraham' as the Lord's Divine itself, which is called the Father, dealt with in 2011, 3251, 3439. And as these words are addressed to Jacob, who is to represent the Divine Good and Truth of the Lord's Divine Natural, it is a joining together of the Divine itself to the good and truth of the Natural - this joining together being meant in the internal sense by 'He will give you the blessing of Abraham'. In the sense of the letter it is possession of the land of Canaan that is meant by 'the blessing of Abraham', and also by the words that follow, 'to inherit the land of your sojournings, which God gave to Abraham'. This also is what these words are taken to mean by all who believe that the historical descriptions of the Word do not embody anything more heavenly and deeper than that. This is especially so with the Jewish nation, which also claims from that sense to hold a superior position to all other nations and peoples. Their forefathers understood those words in the same way, especially Jacob, who had that kind of disposition, as becomes clear from what has been stated just above in 3667. That is to say, he did not know Jehovah and was unwilling to acknowledge Him unless He conferred bodily and worldly benefits on him. The fact that neither Abraham, nor Isaac, nor Jacob were meant, but that Jacob represented the Lord's Natural which He was to make Divine is abundantly evident from the explanations given. The same applies to the character of any person who represents, whether evil or good; for the evil are no less able to represent, and have represented, the Lord's Divine, see 665, 1097, 1361.

[2] The same may be seen from the representatives which also exist at the present day. For all kings, no matter who they are or what they are like, represent the Lord through the kingly office itself residing with them; and in like manner all priests, no matter who they are or what they are like, do so through their priestly office. The kingly office itself and the priestly office itself are sacred, no matter who serves in them. Consequently the Word taught by someone evil is no less sacred; nor is the Sacrament of Baptism, or the Holy Supper, or similar ministrations any less so. From this it may also be seen that no king can possibly claim as his own the sacredness that goes with his kingly office, nor any priest the sacredness that goes with his priestly office. Insofar as he does claim it or attribute it to himself he brands himself with the sign of a spiritual thief, or the mark of spiritual theft. And insofar as he commits what is evil, that is, acts contrary to what is right and fair, and contrary to what is good and true, a king throws off his representation of the sacred kingly office, and a priest his representation of the sacred priestly office, and then represents the reverse of this. This explains why so many laws were laid down in the Jewish representative Church concerning the sacredness which was to be attached in particular to priests when ministering. More on this matter will in the Lord's Divine mercy be stated later on.
