The man is 'plain-looking', the girl is 'homely'. Beauty is supposed to be in the eye of the beholder. Beauty is relative. Some African cultures would use the word 'beautiful' to describe a woman Hollywood would laugh at. Jesus, you believe I am beautiful.

As every 'beautiful' woman knows, she can be treated as simply an aesthetic, sexual object, and that is so belittling. Indeed it's an insult to her personhood. It is, of course, beauty of the spirit that lights the eyes and transforms even a plain woman into a beautiful one. Beauty, says our text is a matter more of inner transformation than outward attraction. The greatest beautifier is a contented heart and a gentle and quiet spirit.
