Jeremiah 31:19

For after I had turned away , I relented , and after I was instructed , I struck my thigh ; I was ashamed , and I was confounded , because I bore the disgrace of my youth .

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.`

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.
