I just became a member of Biblical Archaeology Society and one of the perks is that you, as a member, get access to their back issues of not just Biblical Archaeology Review
, but Bible Review
as well. And so I was looking at some back issues and found this very informative article. For those of you who have always been perplexed by this strange Israelite prohibition the article is here.
Oh, and be sure to look at the interesting images too.
