Isaiah 4:4-5

4At that time, the Lord God will wash away the dirt from Zion's women. He will make Jerusalem clean from the blood that murderers have left. He will do that as judge, and he will punish people as with fire.

5The Lord himself will be above all of Mount Zion, and over all the people who meet together there. There will be cloud and smoke over them during the day. There will be bright flames of fire at night. The Lord's glory will cover over them all.
