John Gill Commentary Ezekiel 24:7

"For her blood is in the midst of her; she set it upon the bare rock; she poured it not upon the ground, to cover it with dust." — Ezekiel 24:7 (ASV)

For her blood is in the midst of her
The blood of innocent persons shed in the midst of her, openly and publicly, cried for vengeance: she set it upon the top of a rock ;
where it could not soak in, as when spilled upon soft earth: this denotes her openness and impudence in shedding blood, as not being ashamed of it, or afraid of punishment for it, but as rather glorying in it; perhaps there may be some allusion to the tops of hills and mountains, where idolatry was committed, attended with shedding human blood: she poured it not upon the ground, to cover it with dust ;
she did not take any methods to hide her sin; having no sense of the heinousness of it, nor any consciousness of guilt, or any remorse or repentance; respect is had to a law which obliged to cover blood shed with dust, (Leviticus 17:13) . The Targum of the whole is,

``because innocent blood which is shed in the midst of her; with pride and with a high arm she shed it; she shed it not through ignorance, that she might repent of it.''
