8935. An altar of ground thou shalt make unto Me. That this signifies a representative of worship in general from good, is evident from the signification of “an altar,” as being the principal representative of the Lord, and consequently of the worship of Him (see n. 921, 2777, 2811, 4489, 4541); and from the signification of “ground,” as being good. That “ground” denotes good is because by “ground” is signified the church which is in good (n. 566). Hence Adam was said to be “from the ground” (Genesis 2:7; 3:19), for by him was signified the man of the celestial church, or the church which is in good (n. 478, 479). There are two things from which the worship of the Lord is effected; good and truth. Worship from good was represented by an altar of ground, but worship from truth was represented by an altar of stones; both kinds of altars are here treated of. These two things from which worship is effected are called faith and charity; worship from truth bears relation to faith, and worship from good to charity. As regards worship from faith and worship from charity, or from truth and from good, the case is this. Before a man is regenerated he is in worship from truth, but when he has been regenerated, he is in worship from good. For before a man has been regenerated he is led by means of truth to good, that is, by means of faith to charity; but when he has been regenerated he is in good and thence in truth; that is, he is in charity and thence in faith (n. 8516, 8539, 8643, 8648, 8658). These two kinds of worship are what are represented by altars of ground and of stone. (That an altar is the chief representative of the worship of the Lord, because thereon were made burnt-offerings and sacrifices, and these were the things in which the Divine worship of the Hebrew nation, and thus of the Israelitish and Jewish nation, chiefly consisted, see n. 923, 1343, 2180, 2805, 2807, 2830, 3519, 6905)

2777. Upon one of the mountains. That this signifies the Divine Love, is evident from the signification of a “mountain,” as being love (see n. 795, 796, 1430); here, the Divine Love, because it is predicated of the Lord; and what the quality of this love is, may be seen above (n. 1690, 1691 at the end, 1789, 1812, 1820, 2077, 2253, 2500, 2572). As it was the Divine Love from which the Lord fought in temptations and conquered, and by which He sanctified and glorified Himself, it is here said to Abraham that he should offer up Isaac for a burnt-offering upon one of the mountains in the land of Moriah. This representative is elucidated by the fact that an altar was built by David, and the temple was built by Solomon, upon the mountain of Moriah (n. 2775); for the altar upon which burnt-offerings and sacrifices were offered, was the principal representative of the Lord, as was afterwards the temple. That the altar was so may be seen above (n. 921); and it is evident in David:

Let them bring me to the mountain of Thy holiness, and to Thy tabernacles; and I will go unto the altar of God, unto God, the gladness of my joy (Psalms 43:3-4

That the temple was so too, is evident in John:

Jesus said, Destroy this temple, and in three days I will raise it up. He spake of the temple of His body (John 2:19, 21).
