Here’s a great link on bad Hebrew tattoos. I occasionally get emails from people asking me to check their Greek or Hebrew tattoos. For one, my Hebrew sucks, so I never offer any advice in that realm. I also get people asking me for advice about Greek – though I’m confident enough to read Homer, I still don’t know that I’m the person you want to talk to about your Greek tattoo. I have one myself (with some Greek from the NT), but I 1) thought about the tattoo for well over 3 years and 2) I checked the Greek about a bazillion times. In fact, I’d strongly advise you not to get a tattoo in a language you don’t know yourself (that’s kind of poseur-ish, isn’t it?).
