The discourse of a godly man is always with wisdom; but a fool changes as the moon.
All Commentaries on Wisdom of Sirach 27:11 Go To Wisdom of Sirach 27
Augustine of Hippo
AD 430
"You have made perfect sun and moon." The sun indicates spiritual people; the moon, carnal ones. As carnal as one is, may he not be forsaken and may he too be made perfect. The sun, as it were, is a wise person; the moon, as it were, is an unwise person. You have not however forsaken either one. For thus it is written, "A wise person endures as the sun, but a foolish person as the moon is changed." What then? Because the sun endures, that is, because the wise person endures as the sun, a foolish person is changed like the moon. Is one who is still carnal, still unwise, to be forsaken? And where is that which has been said by the apostle, "To the wise and unwise a debtor I am"?
