Jeremiah 9:20

Death comes in through (in at) the windows, not because the doors are to be thought of as barricaded (Hitz.), but as a thief in the night, i.e., suddenly, in an unexpected way. Perhaps Jeremiah was here thinking of Joe 2:9. And comes into the palaces, i.e., spares no house, but carries off high and low. The second clause is not to be very closely joined with the first, thus: Death comes into the houses and palaces, to sweep the children from off the streets; this would be self-contradictory. We must rather repeat "comes" from the first clause: He comes to sweep off the streets the child at play. That is: In the houses and palaces, as upon the streets and highways, he will seize his prey.

In this chapter the prophet goes on faithfully to reprove sin and to threaten God's judgments for it, and yet bitterly to lament both, as one that neither rejoiced at iniquity nor was glad at calamities. I. He here expresses his great grief for the miseries of Judah and Jerusalem, and his detestation of their sins, which brought those miseries upon them (Jer 9:1-11). II. He justifies God in the greatness of the destruction brought upon them (Jer 9:9-16). III. He calls upon others to bewail the woeful case of Judah and Jerusalem (Jer 9:17-22). IV. He shows them the folly and vanity of trusting in their own strength or wisdom, or the privileges of their circumcision, or any thing but God only (Jer 9:23-26).

9:20-21 Because of the many deaths in the city, not enough professional mourners were available. The women were urged to quickly teach their daughters to be skilled mourners.
