18 I have indeed heard Ephraim bemoaning himself [thus]: Thou hast chastised me, and I was chastised as a bullock not trained: turn thou me, and I shall be turned; for thou art Jehovah my God. 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. 20 Is Ephraim a dear son unto me? is he a child of delights? For whilst I have been speaking against him, I do constantly remember him still. Therefore my bowels are troubled for him: I will certainly have mercy upon him, saith Jehovah.

Commentary on Jeremiah 31:18-20
(Read Jeremiah 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.
