Of course it's old hat that men who have to talk of their own or one another's humlity or some other good characteristic probably don't have it, but are making a show. Also (around here) that many noticed this in G.C. and found out, when actually dealing with the supposedly "humble" leadership, even just pleading as to fathers (for some), that they were anything but: instead authoritarian, ambivalent, self-important men who are deluded (but can speak soft and smooth when the next controversy erupts).
Well I just found an old scholarly commentators' description of teachers who put on such shows (as I want to note that these days "building leaders and character" isn't just a GC phenomenon, that is, manufacturing men who speak with a certain effemininity mixed with just enough touch of dignity and a sprig of bravado+talking to crowds about how they know and love one another, their hearts, etc.: it really isn't just a GC thing);
Beware of false prophets,.... Or false teachers; for not such who pretended to foretell things to come, but such who set up themselves to be teachers of others, are here meant; see 2 Peter 2:1. It may be queried, whether our Lord has not respect to the Scribes and Pharisees, who sat in Moses's chair, and taught, for doctrines, the commandments of men? and of whose doctrines he elsewhere bids men beware: for whatever plausible pretences for holiness and righteousness might appear in them, they were repugnant to the word of God, and destructive to the souls of men; such as their doctrines of free will, justification by the works of the law, the traditions of the elders, &c. since it follows,
which come to you in sheep's clothing, but inwardly are ravenous wolves; for these "loved to go in long clothing", Mark 12:38.
in a garment which reached to the feet, and was made of the wool of sheep. The Babylonish garment Achan saw and stole, Rab says (r), was , a garment called "melotes": which is the very Greek word the author of the Epistle to the Hebrews uses for sheep skins, persecuted saints wandered about in, Hebrews 11:37 and the gloss upon the place, in the Talmud referred to, says, that this was , "a talith", or "garment of pure wool"; and Jarchi (s) says, that
"it was the way of deceivers, and profane men, to cover themselves, "with their talith", or long garment, "as if they were righteous men", that persons might receive their lies.''
All which agrees very well with the Pharisees, who would have been thought to have been holy and righteous, humble, modest, and self-denying men; when they were inwardly full of hypocrisy and iniquity, of rapine, oppression, and covetousness; and, under a pretence of religion, "devoured widows' houses". Though, it seems, by what follows, that Christ has respect, at least also, to such, who bore his name, and came in his name, though not sent by him, and called him Lord, and prophesied, and cast out devils, and did many wonderful works in his name; who, that they might get the good will and affections of the people, clothed themselves, not in garments made of sheep's wool, but in the very skins of sheep, with the wool on them, in imitation of the true prophets, and good men of old; pretending great humility, and self-denial, and so "wore a rough garment to deceive", Zechariah 13:4 when they were inwardly greedy dogs, grievous wolves, of insatiable covetousness; and, when opportunity offered, spared not the flock to satisfy their rapacious and devouring appetites. The Jews speak of a "wolfish humility"; like that of the wolf in the fable, which put on a sheep skin.
"There are some men, (says one of their (t) writers,) who appear to be humble, and fear God in a deceitful and hypocritical way, but inwardly lay wait: this humility our wise men call , "wolfish humility".''
Such is this our Lord inveighs against, and bids his followers beware of.
