Luke
King James Version (KJV)

“And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.”
King James Version (KJV)
1:35 The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee - The power of God was put forth by the Holy Ghost, as the immediate Divine agent in this work: and so he exerted the power of the Highest as his own power, who together with the Father and the Son is the most high God. Therefore also - Not only as he is God from eternity, but on this account likewise he shall be called the Son of God.
