Luke 1:35-37

35 And the messenger answering said to her, ‘The Holy Spirit shall come upon thee, and the power of the Highest shall overshadow thee, therefore also the holy-begotten thing shall be called Son of God;

36 and lo, Elisabeth, thy kinswoman, she also hath conceived a son in her old age, and this is the sixth month to her who was called barren;

37 because nothing shall be impossible with God.’
