Anyone out there know the Old Testament?

[Racheldigger]

Somewhere in the Old Testament, there's a story about the wife of an Israelite patriarch who was given a divine message that she was going to have a baby, and who laughed in the angel's face because she was so old she couldn't believe it. Can anybody remember the story, and tell me the name of the baby? I've just found out that I'm pregnant a month short of my 48th birthday, and it would be very appropriate!
