And the angel answered and said unto her, The Holy Spirit shall come upon you, and the power of the Highest shall overshadow you: therefore also that holy thing which shall be born of you shall be called the Son of God.

Hippolytus of Rome
AD 235
Had been concealed, and in which obscurity the natural man was hid, and had a veil upon the heart;-when (it was time), then, that the veil should be taken away, and that these mysteries should be seen, Jesus was born of Mary the virgin, according to the declaration (in Scripture), "The Holy Spirit will come upon thee"-Sophia is the Spirit- "and the power of the Highest will overshadow thee"-the Highest is the Demiurge,-"wherefore that which shall be born of thee shall be called holy.".
The light, (therefore,) which came down from the Ogdoad above to the Son of the Hebdomad, descended from the Hebdomad upon Jesus the son of Mary, and he had radiance imparted to him by being illuminated with the light that shone upon him. This, he says, is that which has been declared: "The Holy Spirit will come upon thee".
Of this Spirit Gabriel also spoke to the Virgin, "The Holy Spirit shall come upon thee, and the power of the Highest shall overshadow thee."
