Tertullian
c. A.D. 150–220
“And, behold, six men were coming toward the way of the high gate which was looking toward the north, and each one's double-axe of dispersion was in his hand: and one man in the midst of them, clothed with a garment reaching to the feet, and a girdle of sapphire about his loins: and they entered, and took their stand close to the brazen altar.”
