709. The name "Jehovah" is here used because the subject now treated of is charity. In the preceding chapter, from the ninth verse to the end it is not said "Jehovah" but "God" for the reason that the subject there treated of is the preparation of "Noah" (that is, of the man of the church called "Noah") as to the things of his understanding, which relate to faith; whereas the subject here treated of is his preparation as to the things of the will, which are of love. When the things of the understanding, or the truths of faith, are the subject treated of, the name "God" is used, but when the things of the will, or the goods of love are treated of, the name "Jehovah" is used. For the things of the understanding, or of faith, do not constitute the church, but the things of the will, which are of love. Jehovah is in love and charity and not in faith unless it is a faith of love or of charity. And therefore in the Word faith is compared to "night" and love to "day"; as in the first chapter of Genesis, where the "great lights" are spoken of, it is said that the "greater light" or the sun, which signifies love, should rule the day, and the "lesser light" or the moon, which signifies faith, should rule the night (Gen. 1:14, 16); and it is the same in the Prophets (Jer. 31:35; 33:20; Ps. 136:8, 9; Rev. 8:12).
