Horeb
In Exodus 3:1, this signifies the quality of the good of the Divine Love which would then appear. (Arcana Coelestia 6830)
In Exodus 17:6, this signifies the divine Law. It also signifies the Lord as to the truths of faith. (Arcana Coelestia 8581)
In Psalm 106:19, this signifies idolatrous worship. (Arcana Coelestia 9391[11])
In Exodus 33:6, this signifies the externals of worship, the Word, and the church; for Horeb was the mountainous area around Mt. Sinai, and so signifies divine truth in externals. (Arcana Coelestia 10543)
Nations
'Nations,' as in Jeremiah 25:31, signify falsities. In Genesis 25:23, 'two nations in the womb' signify the natural regarding interior and exterior good. In general, 'nations' signify people in the good of love and charity from the Lord.
