John Trapp on Jeremiah 3:22

Ver. 22. Return ye backſliding children] Give the whole turn, and not the half-turn only. So Act. 2.38. Peter ſaid to them that were already prickt at heart, Repent ye, even to a tranſmentation; and chap. 3.19. Repent ye, and be converted, that your ſins may be blotted out. Repent not only for ſin but from ſin too: be through in your repentance, ſet it be ſuch as ſhall never be repented of, 2 Cor. 7.10. It is not a ſlight ſorrow that will ſerve Apoſtates turn; it muſt be deep and down-right.

And I will heal your back ſlidings] Pardon your ſins, and heal your natures. I will love you freely, and cauſe your broken bones to rejoyce, Hoſ. 14.4. Iſa. 19.22. Oh ſweeteſt promiſe I what wonder then that their hard hearts were forthwith melted by it into ſuch a gracious compliance, as followeth.

Behold we come to thee] See Zach. 13.9. with the Note.
