But the multitude of the wise is the welfare of the world: and a wise king is the upholding of the people.
Read Chapter 6
Augustine of Hippo
One who must speak with wisdom, if he is unable to do so eloquently, must absolutely follow the word of the Scriptures closely. The poorer he is in himself, the more necessary it is that he be rich in the Scriptures, so as to demonstrate, using them, what he says with his own words. And one who is inferior in speaking will in some way grow, thanks to the testimony of what is superior. In fact, the one less able to delight by speaking will delight by demonstrating. One who makes an effort to speak not only with wisdom but also with eloquence will be even more useful if he is skilled in both. Willingly would I allow that a person whom I counsel to follow the masters of rhetorical art read, listen to or practice imitating the eloquent, because those who are read or listened to are known for speaking or for having spoken not only eloquently but also wisely and truly. In fact, those who speak with eloquence do so attractively, whereas those who speak with wisdom are listened to for salvatio...
Only God is declared to be wise. He is defined as wise because he does not receive wisdom from another, nor does he participate in the wisdom of another.

He alone is wise, as opposed to the other beings who are considered wise by his gift ("An abundance of wise people is the salvation of the world," and, further, "Those wh...
Having arrived at Jerusalem, Ezra, inflamed with zeal for the Law, decided first of all to purify the people of their vices, since, as the prophet said, "A wise king is the salvation of his people." Having found the book of Moses, he showed, among other things, that the wrath of God was kindled against the people because they had married foreign wives against God"s commandment. With severity, which was his strength, he convinced them to send back their wives and their children. No longer held back by carnal delights and wanting to propitiate God, they did what was commanded of them without hesitation. In this way they symbolized the Christian people, whom the first among all priests admonishes, "If anyone leaves house, fields, wife or children because of my name, he will be repaid many times over here and will gain eternal life." - "The Book of Promises and Predictions of God 2.37.83"
