9388. 'And built an altar under the mountain' means a representative sign of the Lord's Divine Human in respect of Divine Good from Him. This is clear from the meaning of 'an altar' as a representative sign of the Lord's Divine Human, dealt with in 921, 2777, 2811, 4489, and therefore the chief representative of worship of the Lord, 4541, 8935, 8940; and from the meaning of 'the mountain' as the good of love, dealt with in 4210, 6435, 8327, 8658, 8758, in this instance the Divine Good of love which emanates from the Lord, since it was Mount Sinai, where the Lord was then. 'Mount Sinai' means Divine Good united to Divine Truth emanating from the Lord, see 8805.

2777. 'On one of the mountains' means Divine love. This is clear from the meaning of 'a mountain' as love, dealt with in 795, 796, 1430, here Divine love since it has reference to the Lord. For the nature of that love, see 1690, 1601 (end), 1789, 1812, 1820, 2077, 2253, 2500, 2572. As it was Divine love from which the Lord fought and overcame in temptations, and from which He sanctified and glorified Himself, Abraham is in this verse told to offer Isaac as a burnt offering 'on one of the mountains' in the land of Moriah. Light is shed on this representative act by the fact that David built an altar, and Solomon the Temple, on Mount Moriah, 2775. For the altar on which burnt offerings and sacrifices were offered, and later the Temple, was the chief representative of the Lord. The fact that the altar was the chief representative of Him may be seen in 921 and is clear in David,

They will bring me to Your holy mountain and to Your dwellings. Then I will go in to the altar or God, to God my exceeding joy. Psalms 43:3-4.

And that 'the Temple' was representative of Him is clear in John,

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