15 This Christ, when He had come, the Jews denied, but the devils confessed. But His forefather David was not ignorant of Him, when he said, I have ordained a lamp for mine Anointed: which lamp some have interpreted to be the brightness of Prophecy, others the flesh which He took upon Him from the Virgin, according to the Apostle's word, But we have this treasure in earthen vessels. The Prophet was not ignorant of Him, when He said, and announces unto men His Christ. Moses also knew Him, Isaiah knew Him, and Jeremiah; not one of the Prophets was ignorant of Him. Even devils recognised Him, for He rebuked them, and the Scripture says, because they knew that He was Christ. The Chief-priests knew Him not, and the devils confessed Him: the Chief Priests knew Him not, and a woman of Samaria proclaimed Him, saying, Come, see a man which told me all things that ever I did. Is not this the Christ?
