Приповісті 26:23

The proverbs next following treat of a cognate theme, hypocrisy (the art of dissembling), which, under a shining [gleissen] exterior, (Note: Vid., regarding gleisen (to give a deceitful appearance) and gleissen (to throw a dazzling appearance), Schmitthenner-Weigand's Deutsches Wrterbuch.) conceals hatred and destruction: 23 Dross of silver spread over an earthen vessel - Lips glowing with love and a base heart. Dross of silver is the so-called gltte (French, litharge), a combination of lead and oxygen, which, in the old process of producing silver, was separated (Luther: silberschaum, i.e., the silver litharge; Lat. spuma argenti, having the appearance of foam). It is still used to glaze over potter's ware, which here (Greek, κέραμος) is briefly called חרשׂ for כּלי חרשׂ; for the vessel is better in appearance than the mere potsherd. The glossing of the earthenware is called צפּה על־חרשׂ, which is applicable to any kind of covering (צפּה, R. צף, to spread or lay out broad) of a less costly material with that which is more precious. 23a contains the figure, and 23b its subscription: שׂפתים דּלקים ולב רע. Thus, with the taking away of the Makkeph after Codd., to be punctuated: burning lips, and therewith a base heart; burning, that is, with the fire of love (Meri, אשׁ החשׁק), while yet the assurances of friendship, sealed by ardent kisses, serve only to mask a far different heart. The lxx translate דלקים [burning] by λεῖα, and thus have read חלקים [smooth], which Hitzig without reason prefers; burning lips (Jerome, incorrectly: tumentia; Luther, after Deu 32:33, חמת: Gifftiger mund = a poisonous mouth) are just flattering, and at the same time hypocritical (Note: Schultens explains the labia flagrantia by volubiliter prompta et diserta. But one sees from the Arab. dhal…

This may be meant either, 1. Of a wicked heart showing itself in burning lips, furious, passionate, outrageous words, burning in malice, and persecuting those to whom, or of whom, they are spoken; ill words and ill-will agree as well together as a potsherd and the dross of silver, which, now that the pot is broken and the dross separated from the silver, are fit to be thrown together to the dunghill. 2. Or of a wicked heart disguising itself with burning lips, burning with the professions of love and friendship, and even persecuting a man with flatteries; this is like a potsherd covered with the scum or dross of silver, with which one that is weak may be imposed upon, as if it were of some value, but a wise man is soon aware of the cheat. This sense agrees with the following verses.

26:23-26 People sometimes hide evil attitudes and wicked intentions through flattery. In the end, the true hatred of smooth talkers will be exposed.
