Luke 1:34-36

34 Said but Mary to the messenger: How shall be this, since a man not I know?

35 And answering the messenger said to her: A spirit holy shall come upon thee, and a power of highest shall overshadow thee; therefore and the being begotten holy, shall be called a son of God.

36 And lo, Elisabeth the kinswoman of thee, even she having conceived a son in old age of her; and this month sixth is to her the being called barren.
