305. Verses 4, 5. And I wept much, that no one was found worthy to open and to read the book, neither to look thereon. And one of the elders saith unto me, weep not; behold, the Lion that is from the tribe of Judah, the Root of David, hath overcome to open the book, and to loose the seven seals thereof.

4. "And I wept much, that no one was found worthy to open and to read the book, neither to look thereon," signifies grief of heart on account of the disorder and destruction of all things, if no one could know [scire], cognize [cognoscere], and explore all men, and all things pertaining to men (n. 306).

5. "And one of the elders," signifies a society of heaven superior in wisdom to the rest (n.307); "saith unto me, Weep not," signifies that there need be no grief on that account (n. 308); "behold, the Lion hath overcome," signifies that the Lord from His own power subjugated the hells, and reduced all things in the heavens to order (n. 309); "from the tribe of Judah, the Root of David," signifies by means of Divine good united to Divine truth in His Human (n. 310); "to open the book, and to loose the seven seals thereof," signifies that He knows and recognizes all and each, and the most secret things of everyone (n. 311).

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.
