31:19 Surely after I was turned, I repented; and after I was instructed, I smote upon [my] {z} thigh: I was ashamed, and even confounded, because I bore the reproach of my youth.
(z) In sign of repentance and detestation of my sin.
31:19 Surely - After God had changed our hearts, we repented. I smote - After God had instructed us, by his prophets, by our afflictions, and by his Holy Spirit, we smote upon our thighs in testimony of our sorrow. The reproach - The just punishment of the sins which I had long ago committed.
31:18-20 Ephraim (the ten tribes) is weeping for sin. He is angry at himself for his sin, and folly, and frowardness. He finds he cannot, by his own power, keep himself close with God, much less bring himself back when he is revolted. Therefore he prays, Turn thou me, and I shall be turned. His will was bowed to the will of God. When the teaching of God's Spirit went with the corrections of his providence, then the work was done. This is our comfort in affliction, that the Lord thinks upon us. God has mercy in store, rich mercy, sure mercy, suitable mercy, for all who seek him in sincerity.
