Wherefore thus saith the Lord GOD; Woe to the bloody city, to the pot whose scum is therein, and whose scum is not gone out of it! bring it out piece by piece; let no lot fall upon it.
Woe to the bloody city ... the pot whose scum is therein - not ordinary, but poisonous scum, i:e., the people's all-pervading wickedness.
Bring it out piece by piece - "bring it," the contents of the pot-its flesh; i:e., 'I will destroy the people of the city, not all at the same time, but by a series of successive attacks.' Not as Fairbairn 'on its every piece let it (the poisonous scum) go forth.'
Let no lot fall on it - i:e., no lot, such as is sometimes cast, to decide who are to be destroyed and who saved: as, for instance, David used a line in smiting the Israelites - "With two lines measured he to put to death, and with one full line to keep alive" (2 Samuel 8:2; Joel 3:3; Obadiah 1:11; Nahum 3:10). In former carryings away of captives lots were cast to settle who were to go and who to stay; but now all alike are to be cast out, without distinction of rank age, or sex.
