I agree. Though, just this view alone seems to be working against something in the text too. Yes, the text is bound to its moment, but it also transcends.
How do you bring together the timeless and situated nature of the revelation? I think the instinct behind “plain readings,” at its best, is the vernacularism of Martin Luther and a theological embrace (even if it is linguistically naive at times) of the timeless purpose and work of Scripture.
It seems that Walton’s work on ANE, and others like it, are sometimes troubled with that quality of Scripture too. In many ways, this gets back to some of the many other threads here on OT in relation to NT, and even science.
