Ezekiel 24:6-7
6 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.
7 For her blood is in the midst of her; she set it upon the top of a rock; she poured it not upon the ground, to cover it with dust;
Eze. 24:6, 7. The Law required that they should not eat flesh with the blood, but that the blood should be poured on the ground and covered with dust. Leviticus 17:13. Flesh dressed and eaten with the blood was polluted, abominable flesh. The people of Jerusalem are here compared to such flesh in the caldron. Her blood is in the midst of her; she is like a pot where scum is in the midst of it. When bloody flesh is boiled in a pot, the blood rises in a scum. The sin of the people is compared in these words to two things: (1.) To the blood and scum, which is the pollution and abomination of bloody flesh. (2.) To the wickedness of those that shed blood of men, and did not cover it with earth, as they were required to do the blood of beasts, but were so open and daring in it as to set it on the top of a rock.
Eze. 26:5
