NET
19 For after we turned away from you we repented. After we came to our senses we struck our thigh in sorrow. We are ashamed and humiliated because of the disgraceful things we did previously.’
Darby
19 Surely after that I was turned, I repented; and after I knew myself, I smote upon [my] thigh. I was ashamed, yea, even confounded, for I bear the reproach of my youth.
KJV
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.
