1. If he is associated with the "emergent church" movement, then he IS to be faulted for it denies propositional truth, along with myriad other errors and heresies.
2. This would go a long way to explain how in the world he wrote what he did which he evidently did write, at least from what I gather from what you wrote and the quote provided. Talk about butchering God's divinely inspired Word. Here is what IISam 23:20 says:
2 Samuel 23:20 (ASV) "And Benaiah the son of Jehoiada, the son of a valiant man of Kabzeel, who had done mighty deeds, he slew the two sons of Ariel of Moab: he went down also and slew a lion in the midst of a pit in time of snow."
Sorry, but I can't see much of anything Batterson wrote in this text. And, if nothing else, Benaiah didn't "chase a lion" but rather he killed one that had fallen into a pit.

3. Aside from the total lack of relation to IISam 23:20, I find little of what he wrote in the Bible period, although there are admittedly a couple of things which one could find in part.

In His grace,
