Jeremiah 9:20 - Ellicott's Commentary On The Whole Bible

Teach your daughters wailing. — The thought of Jeremiah 9:9 is continued. The words rest upon the idea that wailing was an art, its cries and tones skilfully adapted to the special sorrows of which it was in theory the expression. They perhaps imply also that death would do its work so terribly that the demand for mourners would be greater than the supply, and that supernumeraries must be trained to meet it. Looking to the many other coincidences between our Lord’s teaching and that of Jeremiah, it is not too much to see in His words to the daughter of Jerusalem, “Weep for yourselves and for your children” (Luke 23:27-28), a parallel to what we read here.
