Jeremiah 9:17 - Matthew Poole's English Annotations on the Holy Bible

Consider ye; either in how sad a condition you are, what circumstances you are under; or rather, bethink yourselves what course to take: and therefore he puts them upon mourning and bewailing their condition, intimated by the following expression. The mourning women; a sort of persons, and principally women, as more apt for passions in this kind, which they had among them, 2 Chronicles 35:25; whose work it was, either to compose funeral elegies, or panegyrics in praise of the dead, and to act them in some mournful manner, as tearing their hair, and beating their breasts, with other mourning postures, or to sing them in some doleful tone, thereby artificially to provoke and excite both passions and expressions of grief in the friends of the deceased, rather wringing out tears than shedding them, in which probably they made greater seeming lamentations than those that did really mourn, as being most concerned; not that God calls upon them to do this as approving the formality, (though this foolish custom had obtained in most ages and countries,) any more than other customs that were made use of by way of illustration; as the Olympic games, and possibly that practice mentioned 1 Corinthians 15:29; but makes use of it, as being customary, either to excite them to and put them upon true repentance, or to convince them hereby that they were not able themselves sufficiently to bewail so great calamities as were coming upon them, intimating hereby that he would give them occasion for the most unfeigned weeping and lamentation. Cunning women; such as are most skilful in it, Amos 5:16; wisdom being taken for skill in any arts, as Exodus 31:3, and elsewhere.
