The Lord's Mark on the Foreheads of the People Who Sigh and Groan

The Lord said to him, pass through the city through Jerusalem and put a mark on the foreheads of the men who sigh and groan over all the abominations that are committed in it. For I shall not spare and you shall show no pity, kill old men outright, young men and maidens, little children and women, but touch no one on whom is the mark and begin at my sanctuary. So they began with the elders who were before the house. This is so intense. It's like God saying, okay, I'm sending my angels and they're going to destroy my holy city.
