The Lord, in the simplest terms, is love itself expressed as wisdom itself. In philosophic terms, love is the Lord's substance and wisdom is His form. Of course, we feel the Lord's love and hear His wisdom in many different ways, depending on our state in life and how receptive we are. That's why the Lord has so many different names in the Bible, and is referred to in so many different ways.
Of all the names, though, “Jehovah” is the most special and most holy, because it refers to the Lord in terms of love, referring to his substance, love itself. Generally, then, we find “Jehovah” used within the context of a church that worships Him, and in connection with people who are growing in their affection for being.
310. From the tribe of Judah, the Root of David, signifies by means of Divine good united to the Divine truth in His Human. This is evident from the signification of "the tribe of Judah," as being all goods in the complex, for all the tribes of Israel signified all truths and goods of heaven and the church (of which above, n. 39; and "Judah" or his tribe signified the good of celestial love (of which see also above, n. 119; and Arcana Coelestia 3654, 3881, 5583, 5603, 5782, 6363); therefore in the highest sense, in which the Lord is treated of, "the tribe of Judah" signifies Divine good. It is evident also from the signification of "the Root of David," as being Divine truth; for by "David" in the Word the Lord in respect to Divine truth is meant (see above, n. 205). Therefore "of the tribe of Judah, the Root of David," means the Lord in respect to Divine good united to Divine truth in His Human. In the Word in the sense of its letter two expressions are mostly used, one involving good but the other truth; but in its internal or spiritual sense these two are joined into one, and this on account of the marriage of good and truth in every particular of the Word (of which see above, n. 238 at end, 288); the reason is that good and truth in heaven are not two but one, for every truth there is of good. The Lord in respect to the Human is called "the Root of David," for the reason that all Divine truth is from Him, even as all things exist and subsist from their root; for the same reason also He is called "the Root of Jesse," in Isaiah:
It shall be in that day that the Root of Jesse, which standeth for a standard of the peoples, the nations shall seek; and His rest shall be glory (Isaiah 11:10).
"Jesse" here stands for David, because he was David's father.
