4815. And Judah went down from his brethren. That this signifies the posterity of Jacob, and specifically the tribe of Judah, which was separated from the rest, is evident from the representation of Judah, as being in the universal sense the posterity of Jacob, and in the specific sense the tribe called the tribe of Judah; and from the signification of "going down from his brethren," as being to be separated from the rest of the tribes, here to go into worse evil than they; for "going down" involves to be cast down to evil, as "going up" involves elevation to good (n. 3084, 4539). The reason of this as before said is that the land of Canaan represented the Lord's kingdom, and Jerusalem and Zion the inmost of it; but the regions outside the boundaries of that land represented those things which are outside the Lord's kingdom, namely, falsity and evil. Therefore going from Zion and Jerusalem toward the boundaries was called "going down;" but going from the boundaries to Jerusalem and Zion was called "going up." Hence "going up" involves elevation to what is true and good, and "going down," to be cast down to what is false and evil. As the falsity and evil to which the tribe of Judah cast itself down are here treated of, it is said that Judah "went down," and then that he "turned aside to a man, an Adullamite;" and by "turning aside" is signified turning to falsity, and afterward to evil.
 It is known that the tribe of Judah was separated from the rest of the tribes, and the reason was that this tribe might represent the Lord's celestial kingdom, but the rest of the tribes His spiritual kingdom. For this reason also Judah in the representative sense is the celestial man, and in the universal sense the Lord's celestial kingdom (n. 3654, 3881); and the rest of the tribes were called by the one name, "Israelites," for Israel in the representative sense is the spiritual man, and in the universal sense the Lord's spiritual kingdom (n. 3654, 4286).
 That the tribe of Judah went into worse evil than the rest is specifically signified by these words: "Judah went down from his brethren, and turned aside." That the tribe of Judah went into worse evil than the rest is evident from many passages in the Word, especially in the prophets; as in Jeremiah:
Her treacherous sister Judah saw when for all the ways whereby backsliding Israel committed adultery I had put her away and given her a bill of divorcement; yet treacherous Judah her sister feared not, but she also went and committed whoredom, so that by the voice of her whoredom the land was profaned, she committed adultery with stone and wood; yet for all these things treacherous Judah hath not returned unto Me; backsliding Israel hath justified her soul more than treacherous Judah (Jer. 3:7-11).
And in Ezekiel:
Her sister indeed saw, yet she corrupted her love more than she, and her whoredoms above the whoredoms of her sister (Ezek. 23:11 to end);
speaking of Jerusalem and Samaria, or of the tribes of Judah and the tribes of Israel. So in many other places.
 In the internal sense that tribe is described as to how it lapsed into falsity, and thence into evil, and at last into mere idolatry. This is indeed described in the internal sense before that tribe was separated from the rest, and before it so came to pass; but what is in the internal sense is Divine, and to the Divine future things are present. (See what is foretold of this nation in Deut. 31:16-22; 32:15-44.)
