Ezekiel 9:4

“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.”

And the LORD said unto him, Go through the midst of the city, through the midst of Jerusalem, and set a mark upon the foreheads of the men that sigh and that cry for all the abominations that be done in the midst thereof.
