4. Then again, speaking of Jerusalem, and of Him reigning there, Isaiah declares, "Thus saith the Lord, Happy is he who hath seed in Zion, and servants in Jerusalem. Behold, a righteous king shall reign, and princes shall rule with judgment." And with regard to the foundation on which it shall be rebuilt, he says: "Behold, I will lay in order for thee a carbuncle stone, and sapphire for thy foundations; and I will lay thy ramparts with jasper, and thy gates with crystal, and thy wall with choice stones: and all thy children shall be taught of God, and great shall be the peace of thy children; and in righteousness shalt thou be built up." And yet again does he say the same thing: "Behold, I make Jerusalem a rejoicing, and my people [a joy]; for the voice of weeping shall be no more heard in her, nor the voice of crying. Also there shall not be there any immature [one], nor an old man who does not fulfil his time: for the youth shall be of a hundred years; and the sinner shall die a hundred years old, yet shall be accursed. And they shall build houses, and inhabit them themselves; and shall plant vineyards, and eat the fruit of them themselves, and shall drink wine. And they shall not build, and others inhabit; neither shall they prepare the vineyard, and others eat. For as the days of the tree of life shall be the days of the people in thee; for the works of their hands shall endure."
