Dave? Well, technically that's the short form of David, which when written in the original Hebrew looks like this.

[He jots down 'דוד'.]

That's without the vowels, and don't ask me to explain Hebrew vowels because you probably don't want to know. Anyway, with the way root words in Hebrew work, it's the same root as 'beloved'. David was the second king of Israel in about... the tenth century BCE. Supposedly, Jesus was descended from him.

[It's not like he ever asked the guy.]
