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.

14. 12. The Word was with God, and God was the Word; and all things were made by Him. In Him was life, and the life was the light of men; He was the true Light which lighteth every man: and the Word became flesh (John 1:1-14).

Father glorify Thy Son, that thy Son also may glorify Thee. Now therefore do Thou, O Father, glorify Me with Thine own self with the glory which I had with Thee before the world was (John 17:1, 5).

N. B. Arcanum. By "to glorify" is meant to unite the Divine Truth with the Divine Good in the Human. The Lord in the Father from eternity was the Divine Good and thence the Divine Truth, wherefore when He descended He was the Divine Truth from the Divine Good; a reciprocal union, or that of the Divine Truth with the Divine Good, was effected by the Lord in the Human while He was in the world: and it was accomplished successively, especially by redemption and by the fact that He did the will of the Father, and then fully by the last temptation, which was that of the cross, for temptation unites. Then was accomplished the reciprocal union of the Divine Truth with the Divine Good, thus the Father and Son are one, thus one Person like soul and body. All Mine are Thine and Thine are Mine, but I am glorified in them (John 17:10).
