Paul Davidson has turned the spotlight on the hoary head of Melchizedek, the guy to who Abraham gave tithes of all (or perhaps it was the other way around!), king of Salem, and had no beginning or end of days. The post is over at the Is That In The Bible blog.
As usual Paul, as he does in all his articles, covers the topic in some depth, but in a very approachable way, with neither apologetics nor obscurantism. I seem to remember being introduced to "the mystery of Melchizedek" through a predictably shallow reprint article from the Plain Truth way back when. Be reassured that this is nothing at all like that!
