9379. 'And they shall not come near' means no separate joining together or presence. This is clear from the representation of Aaron, his sons Nadab and Abihu, and the seventy elders, who are the ones here who 'shall not come near', as the Word in its outward sense, religious teachings, and the Church's leading truths, dealt with above in 9374-9376; and from the meaning of 'coming near' as the Lord's togetherness with and presence among people, dealt with immediately above in 9378, in this instance as no such togetherness or presence, since it says that Moses alone and not they themselves shall come near. The reason why no separate joining together or presence is meant is that Moses at this point represents the Word in general or the Word in its entirety, 9372, as well as the Word in its inward sense, 9374, whereas Aaron, his sons, and the seventy elders represent the Word in its outward sense and the things derived from it. Since there can be no separate joining of these to the Lord, because the Lord is the Word in its entirety, the words of explanation are 'no such joining or any separate presence'.

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.
