Perhaps these mourning women means true weepers, and the cunning women those which were counterfeit. And the counterfeit would have found cause to change their cries into real sorrow, had they foreseen the greatness of the calamities coming upon them. Death entering into the windows, became an affliction, light, and patiently to be borne, as it related to the present life, compared to what the Prophet described, of the miseries at the siege, and in the captivity. See Lamentations 4:1 throughout.
Jeremiah 9:17-22
17 Thus saith the LORD of hosts, Consider ye, and call for the mourning women, that they may come; and send for cunning women, that they may come:
18 And let them make haste, and take up a wailing for us, that our eyes may run down with tears, and our eyelids gush out with waters.
19 For a voice of wailing is heard out of Zion, How are we spoiled! we are greatly confounded, because we have forsaken the land, because our dwellings have cast us out.
20 Yet hear the word of the LORD, O ye women, and let your ear receive the word of his mouth, and teach your daughters wailing, and every one her neighbour lamentation.
21 For death is come up into our windows, and is entered into our palaces, to cut off the children from without, and the young men from the streets.
22 Speak, Thus saith the LORD, Even the carcases of men shall fall as dung upon the open field, and as the handful after the harvestman, and none shall gather them.
