310. Of the tribe of Judah, the root of David. That this signifies by the Divine good united to the Divine truth in His Human, is evident from the signification of the tribe of Judah, as denoting all goods in the aggregate; for all the tribes of Israel signified all the truths and goods of heaven and the church (concerning which see above, n. 39); and Judah, or his tribe, signified the good of celestial love (concerning which also see above, n. 119, and in the Arcana Coelestia 3654, 3881, 5583, 5603, 5782, 6363); hence in the highest sense, in which the Lord is treated of, by the tribe of Judah is signified the Divine good; and from the signification of the root of David, as denoting the Divine truth; for by David in the Word is meant the Lord as to the Divine truth (as may be seen above, n. 205). Hence it is, that by of the tribe of Judah, the root of David, is meant the Lord as to the Divine good united to the Divine truth in His Human. In the Word in the sense of the letter, for the most part, two things are predicated, one of which involves good and the other truth; but those two are conjoined into one in the internal or spiritual sense, and this on account of the marriage of good and truth in each particular of the Word (concerning which see above, n. 238 at end, 288); the reason is, because good and truth in heaven are not two but one; for all truth there is of good. The Lord as to the Human is called the root of David from this, that all Divine truth is from Him, as all things also exist and subsist from their root; hence also it is, that He is called the root of Jesse, in Isaiah:

"And in that day there shall be a root of Jesse, which shall stand for an ensign of the peoples; to it shall the nations seek; and his rest shall be glory" (11:10).

Jesse here stands for David because he was his father.
