'Seir,' as in Genesis 14:6, signifies self-love.

'The land of Seir' signifies in the highest sense celestial natural good of the Lord. It has this meaning because Mount Seir was the boundary of the land of Canaan on one side, as told in Joshua 11:16-17, and all the boundaries, rivers, mountains, and lands, represent the things which were extreme. They take on their representation from the land of Canaan between them, which represents the Lord's celestial kingdom, and in the highest sense, His divine human. The extremes, which are boundaries, are the things called natural levels, because the natural levels are where the spiritual and celestial levels terminate.

To arise and go forth out of Seir, as in Deuteronomy 33:2, signifies that the Lord would make the natural principle divine so that He could become light, or intelligence and wisdom, and so Jehovah, not only regarding His human rational mind, but also regarding His human natural level, which is why says, 'Jehovah arose from Seir,' and 'went forth from Seir.'

'Seir,' as in Genesis 33:14, signifies the conjunction of spiritual and celestial things in the natural level, that is, the truth of faith with the good of charity.

In Deuteronomy 33:2-3, Numbers 24:17-18, Judges 5:4-5, and Isaiah 21:11-12, 'Seir' signifies the good which truth is joined to on the natural level, and in the highest sense, good joined to truth in the Lord's divine natural.

'Mount Seir' denotes the human essence of the Lord.

4384. 'Until I come to my lord, to Seir' means until they - the truth meant by 'Jacob' and the good meant by 'Esau' - could be joined together. This becomes clear from the meaning of 'Seir' as the joining of spiritual things to celestial ones within the natural, that is, the joining of truth which belongs to faith to good which belongs to charity. Good to which truth has been joined within the natural, and in the highest sense the Lord's Divine Natural as regards good joined to truth there, is what is meant strictly speaking by 'Seir' in the following places in the Word: In Moses' prophecy concerning the children of Israel,

Jehovah came from Sinai, and dawned from Seir upon them; He shone from Mount Paran, and came out of myriads of holiness. Deuteronomy 33:2-3.

In Balaam's prophecy,

I see Him, but not now; I behold Him, but not near. A star will arise out of Jacob, and a sceptre will rise up out of Israel. And Edom will be an inheritance, and Seir will be an inheritance, of His enemies - with Israel doing valiantly. Numbers 24:17-18.

In the Song of Deborah and Barak,

O Jehovah, when You went forth from Seir, when You set out from the field of Edom, the earth trembled, the mountains flowed down, this Sinai before Jehovah God of Israel. Judges 5:4-5.

In Isaiah,

One is calling to me from Seir, Watchman, what of the night? Watchman, what of the night? The watchman said, Morning comes, and also the night. Isaiah 21:11-12.
