Ezekiel 24:7

Blood was in Jerusalem’s midst like the blood of a sacrifice that had not been drained out on the ground and covered up (atoned for) as the Law prescribed (Leviticus 17:13). Israel’s sins were open for all to see, like blood on a bare rock (cf. Isaiah 3:9). Not only was Jerusalem a city that had shed much innocent blood, but it was an unacceptable sacrifice to God because of the blood that was in it.
