In fact we have very few physical descriptions of any biblical figure, and the ones we do have are vague, as though what these people looked like is irrelevant. We live in a culture where many seem to consider it important to know how much the president's paramour weighs, or how big his accuser's nose was. Comedians spend almost as much time commenting on Linda Tripp's looks as they do her betrayal of a friend. Guests on a talk show may be taken more seriously if they are attractive than if they are covered with tattoos and have beer guts. Image may mean nothing when the concept is used in a soft drink commercial, but you don't have to think very long to figure out why Michael Jordan and Grant Hill have more commercial endorsements than Dennis Rodman.
Looks drive our society.
Business columnists encourage job seekers to present the best physical image of themselves to prospective employers. Dress up, trim that facial hair, watch the length of your skirt. And studies have shown that given two qualified applicants for a job, the more attractive one tends to get the nod. But the biblical writers seem to think what their subjects did was more important than what they looked like. So the portraits that emerge of our heroes are descriptions of character.
