Bonaventure, on Eccl 10:13

“The beginning of his words is folly, and the end of his talk is a mischievous error.”

“And the reason for precipitousness is indiscretion, because he indiscreetly inclines: whence he says: The beginning of his words is folly. And the reason for this is that he does not consider, whence Proverbs twenty-nine: "Have you seen a man swift to speak? Folly is more to be expected than his correction." He also indiscreetly concludes: whence he says: And the last thing of his mouth is the worst error, because folly in the end leads to an erroneous judgment; Proverbs fourteen: "The imprudence of fools errs"; because, as was said above in chapter two, "the eyes of the wise man are in his head, the fool walks in darkness." Spiritually, his words will be words of blasphemy and pride: therefore foolish and erroneous. Whence it is said, Daniel 11: "He shall speak magnificent things against the God of gods, and shall prosper, until the wrath is accomplished"; and 2 Thessalonians 2: "The man of sin shall be revealed, the son of perdition, who opposes and exalts himself above all that is called God," etc.”
