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.

8915. 'And the voice of the trumpet' means those same truths - Divine Truths from good - going through heaven. This is clear from the meaning of 'the voice of the trumpet' as the state of the angelic heaven which was round about the Divine, and as God's truth from there, dealt with in 8815, 8823. From this one may see what the Lord's words mean where He foretells the close of the age or final period of the Church, at which time,

The Lord will send angels with the loud voice of a trumpet, who will gather His elect from the four winds. Matthew 24:31.

People who do not know that all the Lord's words also have heavenly and Divine things stored within them, that is, that they hold in them an internal sense, will suppose that when the last judgement is imminent angels are going to appear and announce it, and also that they will gather the elect with 'the voice of a trumpet'. But 'the voice of a trumpet' is not used there to mean the sound of a trumpet but God's truth in its inward form spreading through heaven, and the proclaiming of it, see 4060 (end) as well as 8815, 8823.
