2528. 'God said to him in the dream' means a perception that was less obscure. This is clear from what has been stated and explained above in 2514. The reason why in this chapter the name 'God' is used but not 'Jehovah', except in the last verse, is that spiritual matters, that is, matters of doctrine concerning faith, are the subject. For when spiritual matters are referred to, the name 'God' is used, but when celestial matters, that is, love and charity, are dealt with, the name Jehovah' is used, see 709, 732, 2001.

709. The name Jehovah is used because now the subject is charity. From verse 9 to the end of the previous chapter Jehovah is not used but God, the reason being that there the subject is the preparation of Noah, or the member of the Church called Noah, as regards things of his understanding, which are matters of faith. Here however it is the preparation of him as regards the things of his will, which are matters of love. When the subject is the things of the understanding, that is, the truths of faith, the name God is used, but when it is those of the will, that is, goods stemming from love, Jehovah is used. For it is not things of the understanding, that is, of faith, that constitute the Church but those of the will which are matters of love. Jehovah is present within love and charity, but not within faith except faith that inheres in love or charity. This also is why in the Word faith is compared to the night, but love to the daytime, as in Genesis 1 where the great lights are mentioned; the greater light, which is the sun and means love, has dominion over the day, while the lesser light, which is the moon and means faith, has dominion over the night, Genesis 1:14, 16. Similarly in the Prophets, Jeremiah 31:35; 33:20; Psalms 136:8-9; also Revelation 8:12.
