Ezekiel 9:3-4

3Then the glory of the God of Israel rose from above the cherubim, where it had been, and moved to the threshold of the temple. And He called to the man clothed in linen who had the writing kit at his side. 4“Go throughout the city of Jerusalem,” said the LORD, “and put a mark on the foreheads of the men sighing and groaning over all the abominations committed there.”
