"I not an expert on the Bible, but where does it say this?"
He's just being snotty, because his stereotype of Conservatives is that they're all bible-thumpers.
The Bible generally refers to a "Poverty of the Spirit" and how to cure that, though it does instruct us to help others, but not give away the store while we do it. :)
Right. Maybe I'm just being picky here but I don't see a theme of eliminating poverty in the Bible, as this author alleges. Help those in need certainly, eliminate poverty, I haven't seen.
