For there is a shame which brings sin, and there is a shame which is glory and favor. Sirach 4:21
Besides shame, another such ambiguous reality is cleverness which could be quite negative.
There is a cleverness which is abominable, but there is a fool who merely lacks wisdom. There is a cleverness which is scrupulous but unjust, and there are people who distort kindness to gain a verdict. Sirach 19:23, 2579
Yet, cleverness could also characterize a wise man like Sirach himself.
He that is inexperienced knows few things, but he that has traveled acquires much cleverness. I have seen many things in my travels, and I understand more than I can express. Sirach 31(34):1080
Likewise, dreams are an ambiguous reality, Sirach's predisposition is to denigrate dreams as a reliable guide for life.
79 80 Cf. 21:12. Note that panourgia is used in an exclusively positive sense by the Greek translator(s) of Proverbs. It appears in two places: "in order that he might give cleverness (panourgian) to the simple," Prov. 1:4a LXX; "Perceive, 0 simple ones, cleverness (panourgian)!" Pray. 8:5a LXX. Surely, Sirach's translator-grandson was aware of this usage of those responsible for rendering "(the law itself, the prophecies) and the rest of the books" (Sir. prologue, 24-25).
