Ezekiel 9:3-4

3And the glory of the 1God of Israel was gone up from the cherub, whereupon it was, to the threshold of the house; and he called to the man clothed with linen, who had the writer's ink-horn by his side;

4and Jehovah 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 are done in the midst thereof.
