Ezekiel 22:30-31

“I looked for a man from among them who would repair the wall and stand in the gap before me on behalf of the land, so that I would not destroy it, but I found no one.  So I have poured my anger on them, and destroyed them with the fire of my fury. I hereby repay them for what they have done, declares the sovereign Lord.”

I imagine that God was looking for a man like Noah. Jerusalem is in a terrible state as we enter this verse, among the list of sinful practices is: princes using their power to shed blood, making idols, oppression of foreigners and mistreatment of the fatherless and the widow, desecrating the Sabbath, men committing detestable offenses against women. God sought a man to stand in the gap so that the Lord could enact change in Jerusalem and bring life where there is currently only sin and death. God found no man that could do this, and thus Jerusalem is delivered into the hand of Babylon.
