Jeremias 31:19

19 Surely after that I was turned, I repented; and after that I was instructed, I smote upon my thigh: I was ashamed, yea, even confounded, because I did bear the reproach of my youth.

19 After I strayed, I repented; after I came to understand, I beat my breast. I was ashamed and humiliated because I bore the disgrace of my youth.'
