I was quite pleased to finally receive my BDAG and HALOT accordance discs in the mail today. I looked at a few entries in BDAG and was extremely happy at the level of detail present there. I trust it will be an extraordinarily useful resource! As for HALOT, I’ll get back to you when I start learning Hebrew ;-).

You read the OT, right? So I have to imagine that every once in a while you’ll want to look up a word, right? I suspect you’ll use HALOT before you start learning the Hebrew language.
Yeah, I suppose it’ll be useful. I’ve been reading through the Psalms in Greek recently, so it’ll enable me to compare Greek and Hebrew words. I feel rather like many of the early Christians: completely ignorant of Hebrew ;-).
