Luke 1:35-37

35The angel replied, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you. Therefore the child to be born will be holy; he will be called the Son of God.

36“And look, your relative Elizabeth has also become pregnant with a son in her old age – although she was called barren, she is now in her sixth month!

37For nothing will be impossible with God.”
