Mr Block,
I'm not familiar with this way of communication... I apologize if the answer is readily available somewhere else or even here, on this page somewhere.
I'm taking your class on Deuteronomy. When talking about Og's bed in Deut 3.11, you mention that it's during the iron-age. Og's people's "advanced technology" (my expression) made their country all the more intimidating for God's people: if they could make an iron bed, they could make iron weapons.
I find that interesting, and I mentioned that in a conversation. But someone pointed to Genesis 4.22 that already mentions iron work. Now, your comment is puzzling more than it is interesting...
I'm submitting the question respectfully and I truly appreciate your commentary on Deuteronomy (NIVAC) and your video class! Thanks!
