And the angel answered and said unto her, The Holy Ghost (g) shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that (h) holy thing which shall be born of thee shall be (i) called the Son of God.
(g) That is, the Holy Spirit will cause thee to conceive by his mighty power.
(h) That thing which is pure and void of all spot of uncleanliness: for he that was to take away sin must of necessity be void of sin.
(i) Declared and shown to the world to be the Son of God.
