'Conceived' in the Bible

Now after these days, Elizabeth his wife conceived, and hid herself five months, saying,

And behold, Elizabeth, thy kinswoman, she also has conceived a son in her old age, and this is the sixth month to her that was called barren:

And when eight days were fulfilled for circumcising him, his name was called Jesus, which was the name given by the angel before he had been conceived in the womb.
