Jeremiah 31:18; Jeremiah 31:19

18 "I have surely heard Ephraim grieving, 'You have chastised me, and I was chastised, Like an untrained calf; Bring me back that I may be restored, For You are the LORD my God.

19 'For after I turned back, I repented; And after I was instructed, I smote on my thigh; I was ashamed and also humiliated Because I bore the reproach of my youth.'
