Names are interesting things in the Bible.
These days, apart from souvenir key chains and schmaltzy plaques/posters, people (North Americans, at any rate) don't really ascribe too much significance to names, but names – of people or places – tend to be incredibly important in the Bible, so much so that God Himself, now and then, lays down the law and throws a name out there, as a promise or a signifier of some larger plan.
Ishmael, for example. "God will hear." What a promise to a pregnant woman who has run away into the desert after being used in perhaps the most profound way, only to be reviled and, in all likelihood, severely beaten for her trouble.
